IntroductionPostoperative nausea and vomiting (PONV) is among the most common adverse reactions following anaesthesia and surgery. Recent clinical studies have reported that the average incidence is about 30%, while in patients specifically undergoing neurosurgery, the incidence can be as great as 73%. Studies also suggest that its occurrence increases the risk of intracranial haematoma and haemorrhage. The objective of this study is to evaluate the effectiveness of intradermal thumbtack needle buried Neiguan (pericardium 6 (P6)) point therapy in the prevention of PONV in patients undergoing craniotomy under general anaesthesia.Methods and analysisThis is a single-centre, three-arm, randomised controlled trial. 180 participants are randomly assigned to either an acupuncture, intradermal thumbtack needle or control group in a 1:1:1 ratio. The P6 of the acupuncture group is punctured at both sides perpendicularly to a depth of 20 mm. Needles are retained for 30 min and stimulated every 10 min to maintain the de qi. The therapy includes two treatments; the acupuncture is administered immediately after and 24 hours after surgery. For the intradermal thumbtack needle group, the intradermal thumbtack needle is quickly inserted into the skin and embedded at P6 acupoints bilaterally. Patients and their families are asked to press the needlepoint with the onset of nausea, vomiting, bloating, pain and other reported discomforts. The needle is replaced after 24 hours. The therapy is administered immediately after and 24 hours after surgery. For the control group, no intervention is carried out. The incidence of PONV within 48 hours after craniotomy across the three groups is observed. Other observations include: (1) assessment of nausea score (severity of nausea) and pain score (visual analogue scale) 0–2, 2–6, 6–24 and 24–48 hours after craniotomy under general anaesthesia; (2) assessment of total rescue antiemetic dosage 0–48 hours after craniotomy under general anaesthesia; (3) length of hospital stay and (4) patient satisfaction score with PONV management. We will perform all statistical analysis following the intention-to-treat principle.Ethics and disseminationEthics approval has been granted by the Bioethics Subcommittee of the West China Hospital, Sichuan University: the approval number is 2018 (number 231). Results will be expected to be published in peer-reviewed journals.Trial registration numberChiCTR1800017173

Objective: To test the effectiveness of chewing gum in the prophylaxis of postoperative nausea and vomiting (PONV) in patients admitted to the intensive care unit (ICU) after surgery. Design: Prospective, open label, pilot randomised controlled trial. Setting: Two metropolitan ICUs. Participants: Ninety postoperative adult patients admitted to the ICU. Intervention: Patients administered chewing gum, who chewed for at least 15 minutes every 4 hours, were compared with a control group, who were administered a 20 mL sip of water orally every 4 hours. Main outcome measures: The primary outcome was the number of patient-reported episodes of nausea in the first 24 hours after the operation. Secondary outcomes included vomiting or dry retching episodes, and duration and severity of nausea. Results: Forty-six patients were randomly allocated to chewing gum and 44 patients to water. There was no difference between groups in the number of patients with nausea (10 [22%] chewing gum v 12 [27%] control patients; P = 0.72), nausea episodes (22 episodes; [median, 0; IQR, 0–0] v 21 episodes [median, 0; IQR, 0–1] per patient in each group respectively), vomiting/retching (2 [4%] chewing gum v 6 [14%] control patients; P = 0.24), or duration/severity of nausea. Conclusion: Regular postoperative administration of chewing gum in a surgical ICU patient cohort did not reduce nausea, vomiting or retching. The prevalence of PONV is less than previously reported. Our findings can inform future studies of PONV prophylaxis in post-surgical ICU patients. Trial registration: Australian New Zealand Clinical Trial Registry No. ACTRN12617001185358.

This single-blind, randomised, controlled trial was undertaken to assess the efficacy of acupuncture (ACP) at the PC.6 (Neiguan) point in the management of established postoperative nausea and vomiting (PONV) in patients receiving parenteral morphine via a Patient-Controlled Analgesia System (PCAS). Eighty patients were recruited on the first postoperative day and 30 were treated with ACP after developing PONV lasting more than 10min. Patients were randomly allocated to receive ACP bilaterally at either PC.6 or at a dummy point near the elbow, with manual stimulation for a total of 4min. Only patients with no knowledge of ACP antiemesis were studied, and each patient was thus unaware of the group to which they were allocated. Patients treated with PC.6 ACP had a greater mean improvement in their visual analogue score for nausea (p<0.05). All patients in the PC.6 group improved their score by 20% or more, while only one third in the control group did so (p<0.001). In the PC.6 group 53% of patients did not require any further antiemetic while receiving PCAS morphine. All patients in the control group required further antiemetic treatment (p<0.001). No adverse effects were recorded.
