Fig. 2From: Optimal dose of neostigmine antagonizing cisatracurium-induced shallow neuromuscular block in elderly patients: a randomized control studyAnalysis of time of TOF ≥ 90% after neostigmine (min). Time of 20 µg, 40 and 50 µg groups was significantly shorter than that in NS group after administration of neostigmine (all P < 0.001); Time of 40 and 50 µg groups was further significantly reduced compared with that in 20 µg (P = 0.032 and P < 0.001,respectively);yet the time between 40 and 50 µg was comparable (P = 0.249); *P < 0.05Back to article page
