BACKGROUND: Laparoscopic cholecystectomy is presumed to induce a reduction in diaphragmatic activity. Indirect indices of diaphragmatic function based on tidal changes in pressures and cross-section area measurements can be unreliable in the postoperative phase. The present study evaluates diaphragmatic activity by directly recording diaphragmatic EMG (EMGdia) data, along with indirect indices. METHODS: Thirteen adult patients (American Society of Anesthesiologists physical status I or II) undergoing laparoscopic cholecystectomy were examined preoperatively for inspiratory tidal changes in gastric (Pgas-insp) and esophageal (Peso-insp) pressures, and tidal changes in ribcage (Vthor) and abdominal (Vabd) cross-section areas and then again at 1, 6, and 24 h postoperatively combined with EMGdia recordings. Variations in inspiratory gastric (deltaPgas-insp) and inspiratory transdiaphragmatic (deltaPdi-insp) pressures were derived from the above. RESULTS: Laparoscopic cholecystectomy induced a significant reduction in mean deltaPgas-insp, mean deltaPdi-insp, and mean Vabd indicating a reduction of diaphragmatic activity postoperatively. DeltaPdi-insp decreased from 11.8+/-4.0 cm H2O preoperatively to 5.7+/-5.7 cm H2O at 1 h and 6.6+/-5.1 cm H2O at 6 h postoperatively (mean +/- SD; P < 0.05). Vabd decreased from 327.0+/-113.0 ml preoperatively to 174.0+/-65.0 ml at 1 h and 175.0+/-98.0 ml at 6 h postoperatively (mean +/- SD; P < 0.05). These values had partially recovered at 24 h. CONCLUSION: The direct and indirect indices of diaphragmatic activity taken together confirm the presence of reduction in diaphragmatic activity after laparoscopic cholecystectomy followed by its partial recovery at 24 h.
