Postoperative neuromuscular function.
One hundred patients who received a competitive neuromuscular blocking agent during anaesthesia were randomly selected for evaluation of neuromuscular function immediately on their arrival in the recovery room. The anaesthetist was not aware that the patient would be evaluated in the recovery room. Neuromuscular function was assessed by a train-of-four (TOF) ratio, and in conscious and co-operative patients by a series of bedside tests of neuromuscular function. Twenty-one patients had a TOF ratio of less than 0.70 and seven patients a TOF ratio of less than 0.60. Bedside tests of neuromuscular function did not reliably detect this defect in neuromuscular transmission. It is concluded that a relatively large number of patients have a defect in neuromuscular transmission on their arrival in the recovery room, and suggested that this reflects the inadequacy of clinical methods used for the administration and antagonism of competitive neuromuscular blocking agents at this institution.
