Neuromuscular block in Italy: a survey of current management.

BACKGROUND: Little is known about current use of neuromuscular blocking agents by Italian anesthetists. This paper reports the results of a survey conducted to obtain information about current management of neuromuscular block in Italy. METHODS: A questionnaire was given to Italian Anesthetists attending the 64nd National Congress of the Italian Society of Anesthesia, Intensive Care, Analgesia and Intensive Therapy S.I.A.A.R.T.I. (Parma, 13th-16th October 2010). Collected data were stratified by age, geographical location, and the total number of surgical procedures performed in the hospitals concerned. RESULTS: One thousand four hundred forty patients correctly compiled questionnaires were collected. 50% of respondents used clinical tests to monitor the level of neuromuscular blockade. The main clinical tests cited for the evaluation were: keeping the head lifted up for 5 seconds, protruding the tongue and opening the eyes. Train-of-four was used by 50% of respondents on a routine basis. Only 33% of anesthetists reply that a train-of-four ratio of 90% or more is the safe level prior to extubation. CONCLUSION: Clinical signs are used by most of the Italian anesthetists to assess the recovery from neuromuscular blockade. There is poor awareness about their inability to indicate even a significant degree of residual neuromuscular block. A more extensive use of quantitative instrumental monitoring is required for the more rational use of neuromuscular blocking agents.
