Efficacy and safety of remimazolam for procedural sedation during ultrasound-guided transversus abdominis plane block and rectus sheath block in patients undergoing abdominal tumor surgery: a single-center randomized controlled trial

Table 3 Incidences of hypoxemia, injection pain, bradycardia and requirement for rescue sedatives during the nerve block

Variables	Group R	Group M	Group D	P value
Hypoxemia	15(30.0)	12(24.0)	10(20.0)	0.542
Injection pain	12(24.0)	9(18.0)	7(14.0)	0.473
Bradycardia	8(16.0)	10(20.0)	20(40.0)^*#	0.015
Requirement for rescue sedatives	4(8.0)	6(12)	5(10)	0.199

Injection pain was evaluated subjectively with patients verbally reporting their pain level after the first injection.
Hypoxemia = SpO₂ <90%; Bradycardia = HR <60 bpm.
Data are presented as number (%). P<0.05 was considered a statistically significant difference. *, P<0.05 compared with group R; #, P<0.05 compared with group M.
R Remimazolam, M Midazolam, D Dexmedetomidine, SpO₂ Pulse oxygen saturation, HR heart rate.
