Prevalence and time course of postoperative nausea and vomiting and severe pain in patients under general anesthesia with patient-controlled intravenous analgesia. Heliyon 2024; 10:e25160. [PMID: 38322925 PMCID: PMC10844265 DOI: 10.1016/j.heliyon.2024.e25160] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2023] [Revised: 01/05/2024] [Accepted: 01/22/2024] [Indexed: 02/08/2024] Open
Abstract
Introduction Postoperative nausea and vomiting (PONV) and pain are common and distressing complications in patients undergoing surgery. However, it remains uncertain whether timing of the postoperative course or the diel rhythm influences the occurrence of PONV or severe pain. Therefore, we aimed to explore the temporal distribution of PONV and severe pain. Material and methods In this prospective observational study, we enrolled patients aged 18-65 years with American Society of Anesthesiologists classifications I-III, who were scheduled for surgery under general anesthesia. Patients were visited postoperatively at regular intervals (every 6 h over a 24-h period). Incidence of PONV was recorded and categorized based on real-time divisions: before dawn (00:00-05:59), morning (06:00-11:59), afternoon (12:00-17:59), and evening (18:00-23:59) and as sequential periods (i.e., 0-6, 6-12, 12-18, and 18-24 h). Severe pain and use of additional remedies were also recorded. Results A total of 724 patients were included in the final analysis. Of these, 14.92 % experienced PONV within the first 6 h, and 8.29 % received antiemetic therapy. Occurrence of PONV and administration of remedies declined over the 24-h postoperative period. The lowest rate of PONV was observed during the pre-dawn hours (5.66 %). There was no statistically significant difference in the incidence of PONV 24-h postoperatively between surgeries with different end times. Patients underwent orthopedic surgeries had the highest incidence of PONV during 18:00-23:59, gynecological surgery patients had the highest incidence at 12:00-17:59, and 6:00-11:59 for other surgery patients. All patients had the lowest incidence during 0:00-5:59. During the initial 6-h postoperative period, 24.59 % of patients experienced severe pain, which declined in the remaining episodes. Patients who underwent orthopedic and gynecological surgeries exhibited similar temporal patterns and distribution characteristics of PONV and severe pain. Discussion Both PONV and severe pain declined within the 24-h postoperative period, particularly within the first 6 h. Additionally, the onset patterns of PONV vary among patients undergoing different types of surgeries, all patients demonstrated decreased susceptibility to PONV between 00:00-05:59. Our findings enhance prevention and treatment strategies within an optimized timeframe during the postoperative course.

[PMID: 37400984 PMCID: PMC10681530 DOI: 10.1111/iwj.14291] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2023] [Accepted: 06/17/2023] [Indexed: 07/05/2023] Open
Abstract
A meta-analysis study was used to assess whether not placing a drain after thyroidectomy reduces postoperative wound complications. A critical review of the comprehensive literature up to May 2023 was conducted using four databases: PubMed, Embase, the Cochrane Library, and the web of science. Fourteen interrelated studies were reviewed after passing the inclusion and exclusion criteria established by the study and assessing the quality of the literature.95% confidence intervals (Cl) and odds ratios (OR) were calculated using fixed effects models. The data were meta-analysed using RevMan 5.3 software. The results showed that the use of drains during thyroid surgery did not have a favourable impact on patients. Intraoperative placement of drains did not reduce postoperative wound haematoma formation in patients, (OR, 0.86; 95% CI, 0.54, 1.36 p = 0.52). However, the incidence of postoperative wound infection was significantly higher in patients with drains used in intraoperative thyroid surgery, (OR, 0.22; 95% CI, 0.10, 0.45 p < 0.0001). As the sample size of the randomised controlled study used for this meta-analysis was limited, it is important to approach the findings with caution when interpreting the results.Conducting additional high-quality research with larger sample sizes is crucial in order to further confirm these results and reduce the likelihood of duplication.

Abstract
BACKGROUND Postoperative nausea and vomiting (PONV) are common complications that affect the recovery and well-being of elderly patients undergoing gastrointestinal laparoscopic surgery.
AIM To investigate the effect of butorphanol on PONV in this patient population.
METHODS A total of 110 elderly patients (≥ 65 years old) who underwent gastrointestinal laparoscopic surgery were randomly assigned to receive butorphanol (40 μg/kg) or sufentanil (0.3 μg/kg) during anesthesia induction in a 1:1 ratio. The measured outcomes included the incidence of PONV at 48 h after surgery, intraoperative dose of propofol and remifentanil, Bruggrmann Comfort Scale score in the postanesthesia care unit (PACU), number of compressions for postoperative patient-controlled intravenous analgesia (PCIA), and time to first flatulence after surgery.
RESULTS The results revealed a noteworthy reduction in the occurrence of PONV at 24 h after surgery in the butorphanol group, when compared to the sufentanil group (T1: 23.64% vs 5.45%, T2: 43.64% vs 20.00%, P < 0.05). However, no significant variations were observed between the two groups, in terms of the clinical characteristics, such as the PONV or motion sickness history, intraoperative and postoperative 48-h total infusion volume and hemodynamic parameters, intraoperative dose of propofol and remifentanil, number of postoperative PCIA compressions, time until the first occurrence of postoperative flatulence, and incidence of PONV at 48 h post-surgery (all, P > 0.05). Furthermore, patients in the butorphanol group were more comfortable, when compared to patients in the sufentanil group in the PACU.
CONCLUSION The present study revealed that butorphanol can be an efficacious substitute for sufentanil during anesthesia induction to diminish PONV within 24 h following gastrointestinal laparoscopic surgery in the elderly, simultaneously improving patient comfort in the PACU.

The Effect of Transcutaneous Electrical Acupoint Stimulation on High-Risk Patients with PONV Undergoing Laparoscopic Gynecologic Surgery: A Randomized Controlled Trial. J Clin Med 2023; 12:jcm12031192. [PMID: 36769839 PMCID: PMC9917901 DOI: 10.3390/jcm12031192] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2022] [Revised: 01/25/2023] [Accepted: 01/31/2023] [Indexed: 02/05/2023] Open
Abstract
BACKGROUND Postoperative nausea and vomiting (PONV) is one of the most common complications after general anesthesia. The traditional comprehensive management of PONV usually uses one or two drugs, but this regimen fails to meet the requirements of the latest version of PONV guidelines. The purpose of this study was to evaluate the effect of transcutaneous electrical acupoint stimulation (TEAS) on high-risk PONV patients who are undergoing laparoscopic gynecological surgery. METHODS In total, 162 high-risk PONV patients were randomly divided into an experimental group (n = 81) and a control group (n = 81). Both groups were injected with 4 mg of dexamethasone and 0.25 mg of palonosetron. In the experimental group, Nei-guan (PC6) and He-gu (LI4) were stimulated by a transcutaneous acupoint electrical stimulation instrument (HANS200E) 30 min before the surgery. The control group also received electrodes but no stimulation. Variance analysis and rank sum test were used to compare the differences between the two groups. RESULTS The results of the incidence of postoperative nausea, vomiting, NRS score, degree of abdominal distension, and time to first flatus in the experimental group were lower than those in the control group. Nursing satisfaction of the experimental group was higher than that of the control group. CONCLUSIONS The study demonstrates that TEAS combined with dexamethasone and palonosetron can effectively prevent PONV, reduce postoperative abdominal distension and postoperative pain, and shorten the first postoperative flatus time in high-risk patients with PONV. At the same time, it can improve nursing satisfaction.

Effect of Acupuncture on Postoperative Pain in Patients after Laparoscopic Cholecystectomy: A Randomized Clinical Trial. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2023; 2023:3697223. [PMID: 36686975 PMCID: PMC9859706 DOI: 10.1155/2023/3697223] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 07/15/2022] [Revised: 10/18/2022] [Accepted: 10/27/2022] [Indexed: 01/15/2023]
Abstract
Objective To evaluate the efficacy and safety of acupuncture compared to that of parecoxib sodium on postoperative pain (POP), postoperative nausea and vomiting (PONV), and the Bruggemann Comfort Scale (BCS) in patients following laparoscopic cholecystectomy (LC). Methods Eligible patients admitted to the hospital for LC were randomly allocated to either acupuncture or control groups in a 1 : 1 ratio. The subjects in the acupuncture group received acupuncture while those in the control group were injected by parecoxib sodium at their requests. The pain score, PONV score, and BCS were assessed at 0 h, 6 h, 9 h, and 12 h after operation. The primary outcome was the pain score. The secondary outcomes included the number of patients asking for parecoxib sodium from the two groups at 0-6 h and 6-12 h, PONV score, and BCS score. Results The pain score of the acupuncture group were lower in acupuncture than that in the control group at 6 h and 9 h after operation (P=0.002, P=0.008). However, no difference was found at 12 h. Besides, the number of patients administered parecoxib sodium in acupuncture group was less than that in the control group both at 0-6 h and 6-12 h after operation (P=0.019, P < 0.001). Similarly, there were significantly lower levels of PONV score and higher levels of BCS at 6 h after operation in the acupuncture group than in the control group. However, no difference was found at 9 h and 12 h. Conclusion Acupuncture can clinically improve the short-term treatment of postoperative pain after LC and reduce the request for extra analgesics; therefore, acupuncture might be a potential method as one of multimodal analgesia techniques to treat POP following LC.

Effects of Systemic Lidocaine Versus Dexmedetomidine on the Recovery Quality and Analgesia After Thyroid Cancer Surgery: A Randomized Controlled Trial. Pain Ther 2022; 11:1403-1414. [PMID: 36203077 PMCID: PMC9633913 DOI: 10.1007/s40122-022-00442-5] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2022] [Accepted: 09/20/2022] [Indexed: 10/10/2022] Open
Abstract
INTRODUCTION Surgical management is commonly used for thyroid cancer. We evaluated the effects of systemic lidocaine versus dexmedetomidine on the recovery quality and analgesia after thyroid cancer surgery. METHODS A total of 120 patients with thyroid cancer were randomly allocated to group L (received lidocaine 1.5 mg/kg loading, continuously infused 1.5 mg/kg per hour), group D (received dexmedetomidine 0.5 µg/kg loading, continuously infused 0.5 µg/kg per hour) and group C (received normal saline), with 40 cases in each group. Anaesthesia induction and maintenance were performed using target-controlled infusions (TCIs) of propofol and remifentanil. The primary outcome of the quality of recovery-15 (QoR-15) score was recorded on the day before surgery and postoperative day 1 (POD1). Secondary outcomes included the consumption of remifentanil during surgery, time to first required rescue analgesia, number of patients requiring rescue analgesia, postoperative cumulative consumption of tramadol, visual analogue scale (VAS) pain score, incidence of postoperative nausea or vomiting (PONV) and side effects. RESULTS The total score of the QoR-15 at POD1 (median, IQR) was higher in group L (128.0, 122.0-132.8) and group D (127.5, 122.5-132.5) compared to group C (118.5, 113.0-123.5) (P = 0.000). Compared to group C, systemic lidocaine and dexmedetomidine reduced cumulative consumption of remifentanil and VAS pain score (P = 0.000). The time to first required rescue analgesia (mean, SD) was longer in group L (8.1 h, 1.2 h) and group D (8.5 h, 1.9 h) than group C (5.9 h, 0.9 h) (P = 0.000). The number of patients requiring rescue analgesia was lower in group L (8/40, 20%) and group D (6/40, 15%) than group C (16/40, 40%) (P = 0.029), and cumulative consumption of tramadol (mean, SD) was lower in group L (44.0 mg, 17.1 mg) and group D (51.7 mg, 14.1 mg) than group C (73.9 mg, 18.4 mg) (P = 0.000). The incidence of PONV in group L (7/40, 17.5%) and group D (9/40, 22.5%) was lower than group C (18/40, 45.0%) (P = 0.016). Bradycardia (heart rate less than 50 beats/min or lower) was noted in 25 patients (25/40, 62.5%), which was reversed by intravenous administration of atropine 0.5 mg. CONCLUSION Systemic lidocaine and dexmedetomidine had similar effects on enhancing the quality of recovery, alleviating the intensity of pain and reducing the incidence of PONV after thyroid cancer surgery. However, dexmedetomidine may result in bradycardia. Therefore, lidocaine was superior to dexmedetomidine. TRIAL REGISTRATION ChiCTR.org.cn (ChiCTR2000038442). Registered on September 22, 2020.

Abstract
OBJECTIVE Neck circumference (NC) is a simple anthropometric index for the assessment of upper body obesity. Thyroid hormones are closely related to obesity, body fat distribution indicators, and metabolic parameters. However, there are currently no reports on the association between NC and thyroid hormones in the Chinese population. This study aimed to explore the relationship between NC and thyroid hormones in men with normal thyroid function. METHODS A total of 737 euthyroid men from Shanghai communities were enrolled. Anthropometric parameters, including NC and waist circumference (WC), were measured. Serum thyroid hormones were measured by electrochemical luminescence immunoassay. RESULTS NC, WC, and body mass index (BMI) were significantly positively correlated with serum free triiodothyronine (FT3) (all P < 0.05). FT3 levels all presented significant upward trends with the increase in NC, WC, or BMI quartiles (all P for trend < 0.05), whereas there were no significant correlations between the three obesity indices and free thyroxine or thyroid-stimulating hormone (both P > 0.05). After adjustment for metabolic confounding factors such as age, blood pressure, blood glucose, lipid profiles, and CRP in multiple linear regression analysis, the correlation between FT3 and NC disappeared (standardized β = -0.015, P=0.705), and FT3 remained significantly associated with WC (standardized β = 0.103, P=0.012) and BMI (standardized β = 0.082, P=0.047). CONCLUSIONS In euthyroid men from Shanghai communities, there was no independent correlation between serum FT3 levels and NC. The trial was registered with ChiCTR1900024011.

Abstract
OBJECTIVES Intraoperative placement of neck drains in thyroidectomy patients remains a widespread practice, despite prevailing evidence discouraging this practice. This systematic review and meta-analysis was conducted to update the currently available evidence base. METHODS Two independent investigators performed a comprehensive literature search to identify randomized control trials that evaluated postoperative complications associated with neck drains. This was conducted using four databases: Medline, Web of Science, EMBASE, and Cochrane. Identified articles were then screened using a strict eligibility criterion. Sixteen studies were included in the final quantitative analysis and assessed for risk of bias. All methods were in accordance with recommendations from the Cochrane Review Group, U.K. National Health Service Centre for Reviews and Dissemination, and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. RESULTS Our initial search yielded 743 articles. Of those, 16 were included for final quantitative synthesis. The overall analysis demonstrated that postoperative hematomas [pooled odds ratio (OR) = 2.09 (1.04, 4.21); P = .04] and surgical site infections [pooled OR = 3.85 (2.04, 7.28); P < .01] were significantly more likely in the drained group. Furthermore, hospital stays were longer in the drained group [pooled mean difference = 0.88 days (0.56, 1.20); P < .01]. There were no significant differences in fluid volumes within the thyroid bed between study groups [pooled mean difference = -2.30 mL (-4.82, 0.21); P = .07]. CONCLUSION The drained patient group had overall higher odds of hematomas, surgical site infections, and longer hospital stays. Therefore, we recommend against this practice of neck drain insertions in patients who have undergone thyroidectomies. Laryngoscope, 131:690-700, 2021.
