The clinical advantages of painless colonoscopy can reduce the fear and discomfort of patients and increase the detection rate of diseases. Propofol has the characteristics of fast effect and short action time. It is a common choice for painless endoscopic sedation and anesthetics. However, propofol can cause severe respiratory and circulatory depression. Therefore, it is important to find a way to reduce the dose of propofol.
To explore the effect of wrist-ankle acupuncture on propofol dose during colonoscopy.
Two hundred patients who were going to receive selective painless colonoscopy in Hebei Hospital of Traditional Chinese Medicine were selected and divided into wrist-ankle acupuncture group (WAA group, n = 100) and control group (CON group, n = 100). After entering the operation room, patients were given 0.025 mg/kg nabufine intravenously and propofol at the initial dose of 0.5 mg/kg. In patients who did not fall asleep, propofol (10 mg/time) was given until loss of consciousness. Prior to anesthesia, patients in WAA group were punctured by specialist in the inferior 1, 2 and 3 regions according to the zoning principle of wrist-ankle acupuncture. The primary endpoint was required dose of propofol, and the secondary endpoints were the incidence of hypoxemia and hypotension. Furthermore, the following data were recorded: The operation time, wake-up time, incidence of nausea and vomiting, incidence of abdominal distention, post-colonoscopy pain, examiners' satisfaction, patients' satisfaction and Borg fatigue index. This study has been registered in the Chinese Clinical Trial Registry (Registration Code: ChiCTR1900022177).
The induced dose of propofol and the total dose of propofol in WAA group were 80 mg and 110 mg, respectively, which were significantly lower than those in CON group (P < 0.05). The incidences of hypoxemia and hypotension in the WAA group were 2.2% and 3.3%, respectively, significantly lower than those in the CON group (P < 0.05). The incidence of abdominal distension in the WAA group was 8.8%, which was significantly lower than that in the CON group (P < 0.05, 28.9%). The waking time of WAA group was 3.26 ± 0.87 min, which was significantly lower than that of CON group (6.06 ± 0.88 min, P < 0.05).
Wrist-ankle acupuncture can reduce the induction dose and total dose of propofol as well as the incidence of adverse reactions in painless colonoscopy without affecting the satisfaction of examiners and patients. This procedure is simple in operation and easy to promote in clinical practice.
Core Tip: Two hundred patients scheduled for painless colonoscopy were selected and divided into wrist-ankle acupuncture group (n = 100) and control group ( n = 100). The operation time, recovery time, incidence of nausea and vomiting, incidence of abdominal distension, pain after colonoscopy, satisfaction of examiners, satisfaction of patients and Borg fatigue index were recorded. The results showed that ankle acupuncture can reduce the induction dose and total dose of propofol, reduce the occurrence of adverse reactions of painless colonoscopy and does not affect the satisfaction of examiners and patients.
