Studies in volunteers suggest that train-of-four (TOF) ratios >0.9 are needed to retain normal function of muscles involved in upper airway patency, swallowing, and vital capacity breathing. We determined if sex-related differences exist in the relationship between adductor pollicis (AP) TOF ratio and measures of neuromuscular function commonly used to assess recovery from neuromuscular block. ⋯ Sex-related differences exist in the relationship between AP TOF ratio and clinical measures of muscle function used to assess recovery from neuromuscular block. Normalization of AP TOF ratios is recommended because a non-normalized TOF ratio of 0.9 does not guarantee adequate reversal of neuromuscular block.

Postoperative nausea and vomiting (PONV) is common but many episodes may be trivial or transient. The aim of the study was to develop a simple-to-use measure of the intensity and clinical impact of PONV. ⋯ We have devised and validated a simplified PONV impact scale that can be used to identify those with clinically important PONV. The avoidance of clinically important PONV could be used as a quality indicator or outcome measure after surgery.
