Preoperative Acupuncture Reduces Anaesthetic Requirement

Research from France: preoperative acupuncture reduces anaesthetic requirement. A French pilot study suggests that preoperative acupuncture administered to the ear, reduces the dose of drugs needed to achieve subsequent general anaesthesia. A total of 32 patients aged 18 to 65 awaiting elective digestive or gynaecological surgery, were allocated to receive either acupuncture or no acupuncture as a control group. Needles were retained for 20 minutes before administering conventional anaesthetics. The required dose was 18% lower in the acupuncture group. The study authors believe acupuncture may exert its effects in this case via the vagus nerve and parasympathetic nervous system.
