We investigated the cardiovascular effects of pneumoperitoneum and steep head‐up tilt during laparoscopic fundoplication using an intra‐oesophageal Doppler ultrasound probe. Repositioning of the probe proved sufficient to maintain the signal throughout the procedure despite the pneumomediastinum. There was a statistically significant increase in mean arterial blood pressure and a fall in stroke distance but not in systemic vascular resistance. Increasing or decreasing the blood pressure with drugs improved stroke distance. The oesophageal Doppler ultrasound proved a satisfactory method for assessing cardiovascular changes during fundoplication.
