BACKGROUND Because of its alpha and beta agonist properties, norepinephrine infusion is currently being studied for the prevention of spinal hypotension during caesarean delivery. Vasopressor infusions are not always possible if there is an unavailability of infusion pumps. Leg wrapping with crepe bandage is an effective technique for prevention of postspinal hypotension and could be useful in resource-poor settings. OBJECTIVE The aim of this study was to compare the incidence of hypotension with norepinephrine infusion or leg wrapping with a control group in women undergoing caesarean delivery with spinal anaesthesia. DESIGN Randomised, double-blind, controlled trial. SETTING Single centre, tertiary level institute, India. Study period 3 April 2018 to 31 March 2019. PATIENTS One hundred and forty-four women aged 19 to 40 years with a singleton pregnancy. INTERVENTION In group Leg Wrapping, crepe bandage was applied tightly from metatarsus to groin. Group Norepinephrine and the control group received sham leg wrapping. In group Norepinephrine, the women received a norepinephrine infusion according to their body weight, while group Leg Wrapping and the control group received a 0.9% normal saline infusion at a similar rate. All three groups received a 500 ml co-load of Ringer's solution over 15 min. Noninvasive SBP was monitored every 2 min until delivery, and every 5 min thereafter. Any hypotensive event (SBP < 20% of baseline) was treated with an intravenous bolus of norepinephrine (7.5 μg). MAIN OUTCOME MEASURES The primary outcome was the incidence of hypotension. The secondary outcomes were performance error measurements, and the incidences of hypertension, bradycardia, norepinephrine rescue bolus and neonatal outcomes. RESULTS The incidences of hypotension were significantly lower in the norepinephrine infusion group and the leg wrapping groups than the control group (P values 0.021 for both). Performance error calculations showed that SBP was maintained closer to baseline with the norepinephrine infusion. CONCLUSION Norepinephrine infusion and leg wrapping can both reduce the incidence of postspinal hypotension during elective caesarean delivery compared with saline infusion alone.

The incidence of residual paralysis remains high in the postoperative period even after reversal of intermediate-acting neuromuscular blockers when reversal and extubation are done based on clinical features and are minimized with neuromuscular monitoring (NMM). Correlation between the clinical features of neuromuscular recovery and train-of-four ratio (TOFR) in NMM is variable. Complete neuromuscular recovery depends upon various factors such as age, the weight of the patient, and anesthesia-related factors such as depth of neuromuscular blockade, an inhalational agent used, the time interval between the last dose of neuromuscular block, and reversal administration. The incidence of residual paralysis was found to be high when the neuromuscular blockade was reversed with a standard dose of reversal and recent studies have demonstrated that low-dose neostigmine is adequate to reverse the shallow neuromuscular blocking effects. Hence, quantitative NMM should be used for safe practice while conducting general anesthesia.
