lNTRODUCTlON

Wrist-ankle acupuncture was developed by Professor Zhang Χinshu from the Department of Psychiatry and Neurology, the First Affiliated Hospital of the Second Military Medical University of the Chinese People’s Liberation Army. Inspired by acupuncture, acupuncture points and acupuncture method, a therapy gradually developed from practice. Wrist-ankle acupuncture is the abbreviation of wrist-ankle acupuncture therapy. It refers to the method of selecting a specific needle entry point at the wrist and ankle and piercing a certain length along the longitudinal axis of the limb along the subdermis to treat diseases. Compared with other acupuncture therapies, it has the characteristics of simple acupoint selection, long needle retention time, safety and reliability and no side effects. Therefore, the operation of wrist-ankle acupuncture is simpler and does not require electric acupuncture and other equipment,so it is easier to apply in anesthesia[1-2].

Colonoscopy is the gold standard for diagnosing lower gastrointestinal diseases. However, it is an invasive examination that inevitably brings pain to the examinee. To deal with that, painless colonoscopy is commonly applied clinically for examination. The most adopted anesthetics for painless colonoscopy at the moment primarily consist of intravenous anesthetics and anesthetic sedatives,among which propofol and etomidate are the most common ones[3-4]. In terms of its clinical superiority, painless colonoscopy can reduce patients' fear and discomfort and improve the detection rate of disease. Propofol is characterized by quick effect and short action time, which is a common choice of sedative and anesthetics in painless endoscopy. However, propofol can cause severe respiratory and circulatory inhibition. Therefore, it is of great clinical significance to find an approach to reduce the dose of propofol. Recent application of acupuncture anesthesia has gradually achieved good results in the field of digestive endoscopy[5]. Accordingly, this study was carried out to analyze whether wrist-ankle acupuncture during painless colonoscopy can reduce the induction dose and total dose of propofol, so as to reduce the occurrence of related complications.

MATERlALS AND METHODS

Clinical case data

The subjects of this study were 200 patients who were going to receive selective painless colonoscopy in Hebei Hospital of Traditional Chinese Medicine from August 2019 to November 2019. Enrolled patients were divided into wrist-ankle acupuncture group (WAA group,=100) and control group (CON group,= 100) based on the random number table method. Finally, 91 cases were included in WAA group and 90 cases in CON group after the exclusion of 19 cases from the study due to prolonged operation time (＞30 min) (Figure 1).

Operation and anesthesia procedure

Enrolled patients were divided into WAA group and CON group based on the random number table method. The allocation was concealed in an opaque envelope. An anesthesiologist trained in wrist-ankle acupuncture was responsible for unsealing the envelope prior to wrist-ankle acupuncture and then performed accordingly but was not responsible for patient care or collection of variable data related to the research. Another anesthesiologist was only in charge of intraoperative management of all patients and was blinded to patient grouping. Meanwhile, the endoscopist (the same physician for colonoscopy)and the nurse (the same trained nurse) were both blinded to the grouping of patients.

As shown in Table 1, there was no significant difference in sex, age, body mass index and operation time of examination between the two groups (＞ 0.05).

Observational indexes

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.

The examiners' satisfaction and patients' satisfaction: After the examination, the endoscopist and patients used the VAS scale of 0-10 points to evaluate satisfaction with the examination.

Statistical and analysis

Reducing the induction dose and total dose of propofol can greatly decrease the complication related to anesthesia during painless colonoscopy. In this study, the mechanism of wrist-ankle acupuncture to reduce the anesthetic dose may be that acupuncture increases cerebral blood flow[18] and changes the permeability of blood-brain barrier[19], resulting in the enhanced permeability of blood-brain barrier to propofol and accelerated onset time of propofol, thus reducing the induction dose of propofol. Inpractice, our data indicated that many patients had opened their eyes at the end of examination.However, patients in WAA group had less complaints, movements or painful expressions, and there was no impact on the examination of the patients, leading to a reduced propofol dose in this group. The decreased demand for propofol in the process is speculated to be related to the good analgesic effect of wrist-ankle acupuncture[20-22].

SPSS 23.0 (Armonk, NY, United States) and GraphPad Prism 7.0 (San Diego, CA, United States) were used for data processing and plotting. Measurement data of normal distribution is expressed as mean ±standard deviation (`x ± s), and the measurement data of non-normal distribution is represented by median (interquartile spacing).test was used to compare the counting data. Rank-sum test was used for non-normal distribution measurement data in both groups. The measurement data of normal distribution between the two groups were tested by two independent sampletest. Besides, the fatigue index was measured by repeated measurement design analysis of variance.＜ 0.05 indicates the difference was statistically significant.

RESULTS

Comparison of general materials

Patients were informed to keep fasting status for 12 h and receive catharsis prior to the examination with the confirmation that no medication was taken before anesthesia. Prior to anesthesia, patients in WAA group were punctured by skilled personnel in the inferior 1, 2 and 3 regions using the needling instrument of filiform needle (No. 32, 1 inch, 0.25 mm × 25 mm in diameter; Hwato, Suzhou, China)according to the zoning principle of wrist-ankle acupuncture (Figure 2). During the operation, patients in both groups were lying on their left side and were given oxygen by nasal catheter (6 L/min),associated with the monitoring of blood pressure, heart rate and pulse oxygen saturation (SpO). Before the injection, the patients were asked to take several deep breaths, followed by intravenous injection of nabufine (0.025 mg/kg) and infusion of propofol (0.5 mg/kg). After waiting for 5 s, patients who did not fall asleep were given another 10 mg of propofol per time as appropriate. Colonoscopy was not performed until the disappearance of eyelash reflex and no response after calling. When there was movement, frowning and hemodynamic changes (heart rate ＞ 20 times/min, systolic blood pressure ＞20% of the basic value) in the patients during operation, additional propofol (10 mg/time) was provided until the patients were unconscious again. During colonoscopy, there was no need for adding propofol when patients opened their eyes without painful expression or movement.

Comparison of related indexes during anesthesia

As shown in Table 2, the propofol induction dose and total propofol dose of WAA group was 80 mg and 110 mg, respectively, which were significantly lower than those of CON group (＜ 0.05).

The incidence of hypoxemia and hypotension in WAA group was 2.2% and 3.3%, respectively, which were significantly lower than those in CON group (＜ 0.05).

The incidence of abdominal distention in WAA group was 8.8% (8 cases), which was significantly lower than that in CON group (＜ 0.05). There was no significant difference in the incidence of nausea and vomiting between the two groups (＞ 0.05), as listed in Table 2.

Comparison of related indexes after anesthesia

The wake-up time in WAA group was 3.26 ± 0.87 min, which was significantly lower than that in CON group (6.06 ± 0.88 min,＜ 0.05). The VAS score of pain between 15 min and 30 min in WAA group after entering the recovery room was 1.38 ± 0.49 and 0.65 ± 0.48, respectively, which were significantly lower than those in CON group (2.31 ± 0.47 and 1.89 ± 0.32,＜ 0.05). Although the VAS scores of pain between 30 min in both groups were lower than their counterparts between 15 min, the downswing of VAS score in WAA group was even more remarkable than in CON group. Meanwhile, the Borg fatigue index 5 min after entering the recovery room in WAA group was 1.74 ± 0.697, which was significantly lower than that in CON group (＜ 0.05). No statistically significant difference was observed between the two groups in Borg fatigue index 30 min after entering the recovery room (＞ 0.05).

As to patients' satisfaction and examiners' satisfaction about the whole examination, there was no significant difference in the VAS score of patients' satisfaction between the two groups (＞ 0.05), but the VAS score of examiners' satisfaction in WAA group (9.89 ± 0.31) was higher than that in CON group (＜ 0.05) (Table 3).

DlSCUSSlON

Propofol and opioids are the most commonly used painless drugs clinically. However, each of these drugs causes respiratory depression[6], and the combined use of midazolam or propofol with opioids may further increase the risk of hypoxemia and apnea[7-8]. According to the statistics of reviews related to claims in medical accidents, respiratory depression caused by excessive sedation plays a key role in painless treatment of patients' injuries[9]. The rate of respiratory and hemodynamic complications reached 10.?%-14.5% when using propofol for painless treatment[10-11]. Nowadays, attempts have been made to introduce other methods to reduce the dose of propofol, so as to reduce the side effects of propofol. It has been studied that a combined use of naborphine and propofol can provide safer anesthesia effect[12]. Besides, non-pharmaceutical methods, such as acupuncture combined with anesthesia, can also reduce the dose of narcotic drugs. Wrist-ankle acupuncture, among those, is a significantly simple, safe and reliable acupuncture therapy[13]. Wrist-ankle acupuncture can take 5 min to realize the effect of increasing pain threshold[15]. Different from traditional acupuncture, it adopts shallow subcutaneous acupuncture without soreness and pain, which improves patient’s acceptance and achieves easy intraoperative retaining. At present, wrist-ankle acupuncture has a good effect on dysmenorrhea. It is widely accepted that the discomfort related to colonoscopy mainly comes from visceral pain secondary to colon expansion and traction[17]. The authors support the theory that it is similar to visceral pain such as dysmenorrhea. Therefore, wrist-ankle acupuncture was applied to observe its effect on propofol dose during painless colonoscopy.

With α = 0.05 and power = 0.95 as the inspection levels, the mean and the standard deviation of CON group was 145 mg and 72.0, and the mean and the standard deviation of propofol dose was 115 mg and 45 in WAA group, according to the pre-test results. By using a two-tailed test, the sample size of each group was 88 cases by using PASS11.0 statistical software. Considering an escaping rate of 10%, 200 patients were included and randomly divided, with 100 cases in each group.

Hypoxia and apnea caused by respiratory depression and airway obstruction are the most common cardiopulmonary complications of painless colonoscopy[23]. In our study, the incidence of hypoxemia and hypotension in WAA group was less than that in CON group, because wrist-ankle acupuncture can reduce the dose of propofol, especially during induction when there was a concentrated application of propofol, which might induce a higher risk of respiratory inhibition and circulatory fluctuation. In this regard, respiratory depression and hypotension were relieved in patients consequently owing to the reduced propofol dose during induction by using wrist-ankle acupuncture.

Generally, there is a need to pump air into the intestine to expand the field of vision during colonoscopy, which may produce pressure on the intestinal wall. Patients may feel abdominal pain and distention within hours or even days after the examination[24]. The movement of intestine is manifested as circular muscle contraction in fasting state after colonoscopy, which restricts the movement of colonic contents to the distal colon[25]. Abdominal distention after colonoscopy can cause anxiety and discomfort, which greatly reduce the comfort experience of patients. In this study, the incidence of abdominal distention was significantly reduced in WAA group than that in CON group (＜ 0.05). It is believed that wrist-ankle acupuncture can reduce the activity of sympathetic nerve and improve the tension of the vagus nerve to realize their balance[26]. It can thus promote intestinal peristalsis to expel expanding gases rapidly, reduce the incidence of abdominal distention and relieve the anxiety of patients. It is suggested that patients in the WAA group can wake up quickly after anesthesia. This may be related to the decrease in the dose of propofol or the increase in β-endorphin secretion caused by wrist-ankle acupuncture to regulate body fatigue. Inter-group comparison indicated that the wake-up time of WAA group was superior to that of CON group, which may be caused by the decrease of total propofol dose during the whole operation, so that the patients could wake up more rapidly from anesthesia.

Furthermore, the detection result of the Borg fatigue index was better in WAA group than that in CON group 5 min after entering the recovery room. However, no obvious statistical difference was found between the two groups 30 min after entering the recovery room.

It suggests that patients in WAA group have a rapid wake-up from anesthesia. It may be related to the reduced propofol dose, or increased β-endorphin secretion resulted from wrist-ankle acupuncture to regulate human fatigue[27-29].

After the examination of patients in the two groups, the examiners' satisfaction was improved compared with in the CON group. It can be explained that the examination turnover time was shorter in WAA group since patients in this group woke up faster, and thus it was more popular with doctors.Besides, the patients' satisfaction was similar in the two groups although the incidence of abdominal distention after examination was higher in CON group. We believe that it is related to the sufficient communication with patients before examination. Patients have sufficient understanding and expectation of the occurrence of postoperative abdominal distention and thus better postoperative acceptance. Therefore, it has no significant influence on the satisfaction of patients.

TRP通道的發(fā)現(xiàn)為疼痛治療開辟了一個嶄新的領(lǐng)域。與以往的鎮(zhèn)痛藥物不同，以TRP通道為靶點的新型鎮(zhèn)痛藥物能從源頭上消除疼痛的產(chǎn)生。但我們應(yīng)清楚地認(rèn)識到，TRP通道組織分布廣泛，生理功能多樣，以此為靶點的藥物在發(fā)揮鎮(zhèn)痛作用的同時往往伴隨著副作用。TRPV1拮抗劑正是因為具有體溫過高的不良反應(yīng)而阻礙了其在臨床上的應(yīng)用。因此，減少此類藥物的不良反應(yīng)將是研發(fā)的難點。進一步研究TRP通道在疼痛中的作用對于闡明疼痛的發(fā)生機制、治療及相關(guān)藥物研發(fā)具有重要意義。

There was statistically significant difference of VAS scores between the two groups at 5 min and 15 min after entering the recovery room. However, the estimated scores were all ＜ 3 points, and the result has no significant clinical significance in our opinion. The authors consider that it may be attributed to the fact that the pain is generally mild after colonoscopy, and both groups of patients used naborphine,which may cover the symptoms of patients in CON group. There may be differences between the two groups in the case when naborphine is not used.

Meanwhile, naborphine was administrated to patients according to body weight, and thus there was no difference in the dose between the two groups.

Our study was designed as a randomized controlled study with certain limitations. It is necessary to conduct in-depth research and discussion on the related mechanism with respect to the phenomena observed in the study.

CONCLUSlON

In summary, wrist-ankle acupuncture combined with propofol can significantly reduce propofol dose during painless colonoscopy, decrease the incidence of adverse drug reactions, reduce the incidence of abdominal distention after examination, improve examiners' satisfaction and safety of colonoscopy and reduce the wake-up time of patients. Thus, drug anesthesia combined with wrist-ankle acupuncture is a feasible treatment method worthy of clinical application and promotion.
