We studied the hemodynamic response to preoperative emptying of the stomach by means of a gastric tube in 20 non‐fasting non‐premedicated patients aged 39 (24–54) (median and quartiles) presenting for emergency surgery. Systolic and diastolic blood pressure and heart rate increased by 24.4% ( P <0.01), 29.9% ( P <0.01) and 36% ( P <0.01), respectively. Arterial oxygen saturation decreased by 2.1% ( P <0.01). The rate pressure product increased by 68% ( P <0.01), exceeding 20000 (mmHg · min ‐1 ) [2667 kPa · min ‐1 ] in nine patients. The cardiovascular response is of the same magnitude as reported after tracheal intubation without use of analgesies and is likely to cause cardiac ischemia and other adverse effects in patients suffering from coronary artery disease.
