Oral mosapride can provide additional anti-emetic efficacy following total joint arthroplasty under general anesthesia: a randomized, double-blinded clinical trial



We sought to determine (1) whether the addition of prophylactic oral mosapride to a protocol including dexamethasone and ondansetron further reduces postoperative nausea and vomiting (PONV) compared with ondansetron alone or the combination of both; (2) whether preemptive application of oral mosapride provides additional clinical benefits for bowel function and appetite, thus improving functional recovery.


We randomized 240 patients undergoing total hip and knee arthroplasty to receive placebo (Control, n = 80), dexamethasone (10 mg) before anesthesia induction (Dexa, n = 82), or dexamethasone (10 mg) before anesthesia induction as well as oral mosapride (5 mg) before and after surgery (Mosa+Dexa, n = 78). Patients were assessed at 0–6, 6–12, 12–24, and 24–48 h postoperatively. Primary outcomes were incidence and severity of PONV as well as complete response. Secondary outcomes were appetite, time until first defecation and ambulation, patient satisfaction score, and length of hospital stay.


Mosa+Dexa patients showed significantly lower incidence of nausea at 6–12 h (3.8%) and over the entire evaluation period (6.4%), as well as a higher rate of complete response (89.7%) than other patients. Mosa+Dexa patients required less time to achieve first defecation and ambulation, they were hospitalized for shorter time, and they were more satisfied with clinical care.


Addition of oral mosapride further reduced incidence of PONV, especially postoperative nausea, during 6–12 h postoperatively. Moreover, preemptive application of oral mosapride can further improve appetite, bowel function, ambulation and length of hospital stay.

Trial registration

The study protocol was registered at the Chinese Clinical Trial Registry (ChiCTR1800015896), prospectively registered on 27/04/2018.

Peer Review reports


Total hip and knee arthroplasty remain one of the most commonly performed major orthopedic procedures; the number of procedures in most countries has increased rapidly over the past decades [1, 2]. Postoperative nausea and vomiting (PONV) are one of the most common and distressing complications after surgery, especially when the surgery is performed under general anesthesia: PONV occurs in 25–30% of all patients, and the rate can reach 80% among at-risk patients without prophylactic intervention [3, 4]. PONV can lead to dehydration, hypertension and other postoperative morbidities, which may prolong hospital stay and increase risk of readmission, raising healthcare costs [5]. This was a paradox in the circumstance that surgeons and healthcare providers have been shifting their focus from the surgical technique to perioperative management in order to improve patients’ psychological and functional recovery [6].

Several prophylactic interventions have been reported to prevent and treat PONV, e.g. 5-HT3 receptor antagonists, NK-1 receptor antagonists, corticosteroids, butyrophenone and antihistamines [7]. While these measures can be effective, PONV remains a persistent problem [8, 9]. One reason for this persistence is the gap between implementation and our goal of a “PONV-free hospital”. We previously found that PONV occurred in up to 48.8% of patients undergoing total joint arthroplasty under general anesthesia at our medical center (unpublished data). Another reason for this persistence is that anti-PONV measures can be associated with adverse effects. For example, use of the 5-HT3 receptor antagonist ondansetron can aggravate the postoperative constipation that occurs in up to 65% of total joint arthroplasty patients [10]. We have shown that low-dose dexamethasone can reduce the incidence of PONV following total hip and knee arthroplasty [11, 12], but it can be contraindicated in the presence of diabetes or gastrointestinal ulcers. Therefore, it’s necessary and practical to search for other antiemetic protocol.

The major risk factor of PONV is use of opioids, which can stimulate the release of 5-HT and inhibit gastrointestinal peristalsis [13]]. Indeed, selective 5-HT4 agonists can stimulate the gastrointestinal tract and promote motility [14]. The selective 5-HT4 agonist mosapride can reduce vomiting caused by chemotherapy [15]. This inspired us to examine whether the anti-emetic effects of oral mosapride might offer clinical benefits for total joint arthroplasty patients.

Thus, we sought to determine in the present study (1) whether the addition of prophylactic oral mosapride to a protocol including dexamethasone and ondansetron can further reduce PONV compared with ondansetron alone or the combination of both; and (2) whether preemptive application of oral mosapride can provide additional clinical benefits for recovery of bowel function and appetite.


Study design

This prospective, randomized, clinical trial was performed on patients undergoing primary total hip or knee arthroplasty between November 2017 and December 2018. Institutional review board approval (2012–268) was obtained before the enrollment of patients. All patients provided written informed consent and research authorization before surgery. The study was conducted in compliance with the recommendations of the CONSORT Statement and the Declaration of Helsinki. The study protocol was registered at the Chinese Clinical Trial Registry (ChiCTR1800015896).


Eligible patients included those at least 18 years old who were at risk of PONV (at least 1 score of Apfel), and scheduled for primary total hip or knee arthroplasty for end-stage joint diseases such as osteoarthritis, development dysplasia of hip, and osteonecrosis of the femoral head. Exclusion criteria included a history of intolerance of any drugs used in the current study, administration of another anti-emetic drug or systemic steroid within 24 h before surgery, allergy to experimental drugs or history of adverse reactions, diabetes with poor blood glucose control, history of steroid or immunosuppressive drug use within the previous 6 months, history of cardiac disease such as heart failure, heart block, ventricular arrhythmia or severe impairment of bowel motility, renal function or hepatic function.

Randomization and treatment

Patients in this double-blind study were randomly allocated into three groups using a computer-generated randomization list in a 1: 1: 1 ratio. A random allocation sequence concealed in opaque sealed envelopes only opened before surgery. The control group received 2 ml of normal saline during anesthesia induction, followed by oral placebo at 3 h before surgery and three times per day after surgery. The Dexa group received 10 mg of dexamethasone (in 2 ml) during anesthesia induction, as well as oral placebo at 3 h before surgery and three times per day after surgery. The Mosa+Dexa group received 10 mg of dexamethasone (in 2 ml) during anesthesia induction, as well as 5 mg of oral Mosapride at 3 h before surgery and three times per day after surgery. Dexamethasone was administered intraoperatively by the anesthesiologist and oral drugs were given postoperatively by nurses who were not involved in the study. Patients, surgeons, data collectors and analysts were blinded to group allocation.

Anesthesia and perioperative pain management

All surgeries were performed under general anesthesia by the same surgeons; standard medial parapatellar arthrotomy was performed for total knee arthroplasty, and the posterolateral approach was used for total hip arthroplasty. A cemented posteriorly stabilized prosthesis was implanted in all total knee arthroplasty patients, and cementless acetabular and femoral components were implanted in total hip arthroplasty patients.

All patients received the same anesthetic regimen and multimodal pain management protocol. Cefuroxime (1.5 g) was given intravenously as prophylactic antibiotic prior to incision. Sufentanil (0.2 μg/kg) propofol (2 mg/kg), atracurium (1 mg/kg) and midazolam (2 mg) were used for anesthesia induction. Then sufentanil (0.1 μg/kg), atracurium (0.5 mg/kg) and sevoflurane (1–3%) were used to maintain anesthesia during surgery. After prosthesis insertion, propofol (4 mg per kg per h) and remifentanil (0.1 μg per kg per min) were used to maintain anesthesia. Anesthetic drugs were discontinued before wound closure. At the end of surgery, 8 mg ondansetron was administered intravenously to all patients.

After prosthesis insertion, a periarticular infiltration of 200 mg ropivacaine (100 mg per 10 ml) in 60 ml of normal saline was injected all around the capsule before closure. A dose of 40 mg of parecoxib was injected intravenously to manage pain. Postoperative pain control consisted of 50 mg of oral voltaren (Diclofenac Sodium Sustained Release Tablets) and 10 mg of oxycodone every 12 h. Breakthrough pain was recorded using a Visual Analgesic Scale (VAS) score that ranged from 0 (no pain) to 10 (most severe). If the VAS score was > 6, 50 mg of pethidine was given as an intramuscular injection when required, up to every 6 h. No nerve block or intravenous patient-controlled analgesia was utilized perioperatively.

Outcome measurements

The primary outcome variables were the incidence of PONV, severity of PONV and complete response. Secondary outcome variables included time until first defecation and ambulation, postoperative appetite score, patient satisfaction score and length of hospital stay. A blinded clinical investigator reviewed the diagnosis and medical histories of patients and prospectively collected demographic data and surgical information. The investigator also recorded all episodes of nausea and vomiting, severity of nausea, requirement for anti-emetic rescue, and complete response during four postoperative periods (0–6, 6–12, 12–24 and 24–48 h). Nausea was defined as a subjective unpleasant sensation associated with awareness of the urge to vomit, and vomiting was defined as the forceful expulsion of gastric contents from the mouth [16]. The incidence of nausea and vomiting was determined in each of the four periods and during the entire study by calculating the proportion of patients who experienced PONV. In order to avoid double counting, the patients experienced both nausea and vomiting would be counted as episode of vomiting. Following institutional guidelines, 10 mg of intramuscular metoclopramide was used as a first-line anti-emetic rescue treatment when patients experienced two or more episodes of PONV within 2 h. This was followed by 4 mg of intravenous ondansetron when two consecutive boluses of metoclopramide alone, delivered 30 min apart, were ineffective.

We used a standardized scoring algorithm to classify the severity of PONV on a 4-level scale during the 48-h observation period. Complete response was defined as no additional PONV or no requirement for anti-emetic rescue. Mild PONV described the occurrence of mild nausea or one episode of vomiting caused by exogenous stimulus (drinking or movement). Moderate PONV referred to when the patient vomited up to two times or experienced nausea that required anti-emetic rescue only once. Patients were classified as having severe PONV if they suffered more than two emetic episodes or required more than one dose of rescue anti-emetic [17, 18].

The same blinded investigator also recorded the time until first defecation, ambulation and length of hospital stay, and evaluated appetite score on postoperative days 0–2 as follows: 1 point, lower appetite than preoperatively; 2 points, same appetite as preoperatively; and 3 points, more appetite than preoperatively. The same investigator assessed patient satisfaction before discharge using a VAS score that ranged from 0 (extremely dissatisfied) to 10 (very satisfied). During the perioperative period, all the patients would be carefully evaluated for side effects and cardiac complications such as atrioventricular block, or QT interval prolongation with the use of electrocardiogram if necessary.

Statistical analysis

We performed a priori power analysis based on our preliminary results showing that PONV incidence was 49% in patients receiving ondansetron prophylaxis alone after total joint arthroplasty [unpublished data]. We calculated that 228 patients (76 in each arm) were required to detect a 50% reduction in PONV incidence at an alpha level of 0.05 and a power of 0.9 using a two-sided test. To allow for exclusions and dropouts, we aimed to enroll 246 patients.

Inter-group differences in categorical variables such as incidence of PONV or proportion of complete response were assessed for significance using the chi-square or Fisher’s exact tests. When differences were significant, multiple comparisons between groups were performed using a Bonferroni-corrected post hoc test. Inter-group differences in continuous variables were assessed for significance using either one-way ANOVA, in the case of body mass index, length of hospital stay, time until first defecation or ambulation; or the Wilcoxon signed-rank test, in the case of appetite and patient satisfaction scores. When differences were significant, multiple comparisons between groups were performed using a post hoc Tukey test. Differences associated with p <  0.05 were considered statistically significant. All statistical analyses were conducted in SPSS 21.0 (IBM, Chicago, IL, USA).


A total of 82 patients were initially allocated to each of the three groups. We excluded two patients from the control group and four from the Mosa+Dexa group because of incomplete data and spinal anesthesia. In the end, 240 patients (80 in the control group, 82 in the Dexa group and 78 in the Mosa+Dexa group) were included in the final analysis (Fig. 1). These groups showed no significant differences in clinical or demographic characteristics (Table 1).

Table 1 Baseline characteristics of all patients

Prophylactic use of concurrent dexamethasone and oral mosapride reduced the overall incidence and severity of PONV, and improved the overall complete response during the entire 48-h evaluation period. Across the entire evaluation period, incidence of postoperative nausea was lowest in the Mosa+Dexa group (6.4%), followed by the Dexa group (19.5%) and the control group (43.8%) (p <  0.01 for all, Table 2). Similarly, incidence of postoperative vomiting was lowest in the Mosa+Dexa group (3.9%), followed by the Dexa group (6.1%) and the control group (11.2%), although these differences were not significant (p = 0.176). The rate of complete response was significantly higher in the Mosa+Dexa group (89.7%) than in the Dexa group (74.4%, p = 0.012) or control group (45%, p <  0.001). The rate of severe PONV was significantly lower in the Mosa+Dexa group (1.3%) than in the Dexa group (7.3%, p = 0.062) and control group (18.8%, p <  0.001).

Table 2 Incidence of PONV during the first postoperative 48 h

Simultaneous application of mosapride and dexamethasone reduced the incidence of nausea mainly during the first 12 h (Tables 3 and 4): the incidence during 6–12 h was significantly lower in the Mosa+Dexa group (3.8%) than in the Dexa group (15.9%, p <  0.016) and control group (32.5%, p <  0.016). Moreover, all vomiting episodes occurred during the first 12 h in the Mosa+Dexa patients, while some vomiting incidents in other groups occurred later (Table 4). Nevertheless, the vomiting incidence during the first 12 h did not differ significantly among the three groups. Less patients in Mosa+ Dexa group (2.6%) required rescue treatment for PONV when compared with Dexa group (9.8%, p = 0.06) and Control group (21.3%, p <  0.001, Table 5), as well as total dose of metoclopramide. No significances were detected among the three groups regarding the postoperative pain score and rescue requirement.

The preemptive use of mosapride also reduced the time until first defecation, which was significantly shorter in the Mosa+Dexa group (36.4 ± 18.3 h) than in the Dexa group (54.7 ± 15.8 h, p <  0.001) and control group (60.7 ± 24.6 h, p <  0.001; Table 6). Appetite score was significantly higher in the Mosa+Dexa group than in the control group on postoperative days 0 (p = 0.019), 1 (p <  0.001) and 2 (p = 0.022); and higher than in the Dexa group on postoperative day 1 (p = 0.001; Table 6). Patients in the Mosa+Dexa group began to ambulate 20.6 ± 5.9 h after surgery, significantly sooner than patients in the Dexa group (23.4 ± 5.8 h, p = 0.005) or control group (23.3 ± 4.6 h, p = 0.008). Patients in the Mosa+Dexa group were more satisfied with their hospital experience than patients in the control group (p <  0.001) and Dexa group (p = 0.008). Length of hospitalization was shorter in the Mosa+Dexa group than in the contrl group (4.9 ± 1.4 vs 5.6 ± 1.5 d, p = 0.012).

Table 6 Other clinical outcomes

No adverse events associated with mosapride including prolonged QT syndrome were observed during the study or follow-up. A total of 5 patients (including 1 abdominal pain, 2 dry mouth, 2 insomnia) experienced side effects in control group, 5 patients (1 diarrhea, 1 dry mouth, 3 insomnia) in Dexa group and 6 (in abdominal pain, 2 dry mouth and 3 insomnia) in Mosa + Dexa group without significance (p = 0.908, Table 7).

Table 7 Adverse events and side effects


PONV remains a challenge in recovery after total joint arthroplasty surgery, because it creates anxiety in patients, lowers their appetite, delays ambulation and even disturbs water and electrolyte balance. This increases risk of postoperative complications and prolongs hospitalization and consensus guidelines have been formulated for the management of PONV [7]. Fifteen years have passed since the first international recommendations for the prophylaxis and treatment of PONV [19], and the incidence of PONV has fallen from approximately 80% to 20–30% [20], which is still relatively high. Our own work suggests that at least certain patient populations may show much higher incidence: we reported, for example, 48% incidence in patients who underwent total joint arthroplasty with general anesthesia [unpublished data]. Indeed, risk of PONV appears to be 11-fold higher when surgery is performed under general anesthesia than under regional anesthesia [21]. While modification of risk factors should be taken firstly according to the recommendation of latest consensus [7], some risk factors such as gender or history of smoking and PONV were non-modifiable. Moreover, in our country, total joint arthroplasty is performed under general anesthesia routinely, because of the different medical system. On the other hand, spinal anesthesia is conductive to early ambulation and postoperative anticoagulation following enhanced total joint arthroplasty. These considerations highlight the need to improve PONV prophylaxis and treatment.

In our current study, we compared a new multimodal PONV prophylaxis protocol with a traditional anti-emetic protocol involving ondansetron and/or dexamethasone. The latter two drugs are the most commonly used perioperatively to prevent PONV. Our results indicate that addition of the oral prokinetic drug mosapride can lead to lower PONV incidence and severity, especially postoperative nausea, during the first 12 h postoperatively than the use of ondansetron alone or in combination with dexamethasone, although the difference of severe PONV rate between Dexa + Mosa group and Dexa Group was not statistically significant (p = 0.062). Moreover, preemptive application of oral mosapride can improve appetite, bowel function, time until ambulation and length of hospital stay.

5-HT3 receptor antagonists and corticosteroids are the anti-emetic drugs most commonly used perioperatively to prevent and treat PONV. These drugs act by antagonizing 5-HT3 receptors both peripherally on vagal afferents and centrally in the area postrema. Dexamethasone is a synthetic glucocorticoid showing higher potency, greater bioavailability, and longer acting time than the most widely used antagonist, ondansetron [22,23,24]. Low-dose systemic dexamethasone can show good anti-emetic efficacy [25, 26], although the mechanism remains unclear. The drug may inhibit prostaglandin synthesis and endogenous opioid release, controlling pain and reducing the need for opioid drugs, which can help prevent PONV. The half-life of dexamethasone is about 36–72 h, much longer than the 4 h of ondansetron [22, 23]. Therefore, the combination of dexamethasone and ondansetron can be particularly effective at reducing PONV incidence during the first 12–48 h after surgery (Tables 3 and 4). We found that combining dexamethasone with ondansetron led to lower incidence of PONV and higher incidence of complete response than with ondansetron alone. Similarly, previous work showed that combining dexamethasone with ramosetron further reduced postoperative emesis and pain without increasing risk of wound complications [27]. Studies also have suggested that dexamethasone can help reduce postoperative pain and inflammatory responses [11, 12, 24, 27, 28], which we did not examine here. Future work should explore the full range of benefits offered by dexamethasone.

Here we investigated additional clinical benefits of the anti-emetic mosapride, a selective 5-HT4 receptor agonist. Mosapride can promote the release of acetylcholine and stimulate the gastrointestinal tract to promote motility, thereby improving the gastrointestinal symptoms of patients with functional dyspepsia. Mosapride can inhibit emesis induced by selective serotonin reuptake inhibitors (SSRIs) in laboratory animals [14], probably by reversing the SSRI-induced delay in gastric emptying. We found in the present study that the preemptive use of oral mosapride can provide additional anti-emetic effects beyond dexamethasone and ondansetron in total joint arthroplasty patients. In fact, mosapride may antagonize the ability of 5-HT3 receptor antagonists to reduce gastrointestinal motility, which may help reduce the risk of constipation that affects many total hip and knee arthroplasty patients [29]. Indeed, this motility-inducing effect may help explain why the patients in our Mosa+Dexa group showed better postoperative appetite and shorter times to first defecation and ambulation than patients who did not receive mosapride. Although some patients in Mosa + Dexa group experienced digestive side effects such as abdominal pain or dry mouth, we could not conclude the correlation between mosapride and these side effects because of non-significant difference.

As far as we know, our study provides comprehensive evidence supporting the potential clinical benefit of prokinetic drugs following total joint arthroplasty, although the results need to be interpreted in light of the following limitations. First, patients receiving mosapride alone were not included. Therefore, we cannot make the conclusion that mosapride alone was effective at reducing PONV incidence after total joint arthroplasty. Although our results implicated no incidence of prolonged QT syndrome, more further works are needed to confirm and extend our results, especially the safety profile of mosapride, because another 5-HT4 agonist that antagonizes 5-HT3 activity and that can rapidly relieve nausea induced by SSRIs was withdrawn for cardiotoxicity [30]. Second, the sample number was calculated according to our primary outcome of PONV incidence. As a result, the sample may not have been adequately powered to detect inter-group differences in secondary outcomes, such as rate of severe PONV, and complication rates. Nevertheless, previous work from our group and others suggests that perioperative dexamethasone does not increase the incidence of postoperative infection in total hip and knee arthroplasty [11, 12, 31]. Third, all participants in our study were Chinese and most (67%) were women. Thus, our findings may not be widely generalizable, because female gender is a well-established risk factor for PONV [32]. Fourth, our postoperative analgesic regimen included extensive multimodal pain control drugs and modalities such as preemptive analgesic medication and periarticular injection, which may have introduced heterogeneity into our sample. However, the rest VAS pain score at postoperative 24 h and 48 h and requirement of rescue treatment for pain were comparable among the three groups (Table 5). Fifth, our study did not investigate whether the choice of PONV management regimen affected postoperative inflammatory marker levels and pain control. This should be explored in future work, since our previous study has shown that low-dose dexamethasone can relieve postoperative pain and postoperative nausea, as well as provide additional inflammatory control and improve clinical outcomes [28]. Lastly, our study excluded diabetic patients, so future work should examine whether our results can be generalized to this patient subpopulation.


Prophylactic use of concurrent dexamethasone and oral mosapride can reduce overall incidence and severity of PONV, especially postoperative nausea, as well as increase complete response rates during the first 12 h after total hip and knee arthroplasty when compared with other patients. While it seemed that oral mosapride would not provide additional effect on reducing the rate of severe PONV when compared with dexamethasone alone. Preemptive oral mosapride can also improve postoperative appetite and bowel function.
