Background: Postoperative sore throat (POST) is a common postoperative complication.
Complication: Chewing gum can inhibit the growth of oral bacteria, cleanse, and lubricate the oral cavity, which can help reduce postoperative sore throat. We hypothesize that chewing gum before surgery could relieve POST.
Purpose: Prophylactic intravenous nalbuphine was administered to observe its median effective dose (ED) in reducing pain after undergoing laparoscopic total hysterectomy. To investigate the effect of different doses of nalbuphine on postoperative analgesia and adverse reactions in patients.
Patients And Methods: The 120 patients undergoing laparoscopic total hysterectomy were divided into 6 groups: group C (control) and group P (5 different doses of nalbuphine) with 20 patients per group.
Study Objective: To investigate the effect of propofol-based total intravenous anesthesia (TIVA) or sevoflurane-based inhalation anesthesia on postoperative quality of recovery in patients undergoing total laparoscopic hysterectomy.
Design: A prospective randomized controlled trial.
Setting: An operating room, a postoperative recovery area, and a hospital ward.
Article Synopsis
- The study investigates the impact of intraoperative positioning during cesarean delivery, specifically comparing 15° and 30° left-tilt positions against a supine position, on fetal acid-base balance and maternal hemodynamics.
- Seventy-five patients were randomized, and although there were no significant differences in umbilical arterial pH across the groups, the 30° left-tilt group required less vasoactive medication to manage hypotension.
- The findings suggest that while the 30° position may not significantly improve fetal acid-base balance, it could enhance maternal stability during the procedure by reducing the need for medication compared to the supine position.
Background: Acute renal injury (AKI) caused by hypotension often occurs in elderly patients after gastrointestinal tumor surgery. Although vasoactive drugs can increase effective filtration pressure, they may increase renal vascular resistance and reduce renal blood flow. The effect of methoxamine on renal function is not clear.

This study aimed to investigate whether different doses of magnesium sulfate can effectively attenuate the pneumoperitoneum-related hemodynamic changes and the release of vasopressin in patients undergoing laparoscopic gastrointestinal surgery.
Methods: Sixty-nine patients undergoing laparoscopic partial gastrectomy were randomized into three groups: group L received magnesium sulfate 30 mg/kg loading dose and 15 mg/kg/h continuous maintenance infusion for 1 h; group H received magnesium sulfate 50 mg/kg followed by 30 mg/kg/h for 1 h; and group S (control group) received same volume 0.
Background: Goal-directed volume expansion is increasingly used for fluid management in mechanically ventilated patients. The Pleth Variability Index (PVI) has been shown to reliably predict preload responsiveness; however, a lot of research on PVI has been published recently, and update of the meta-analysis needs to be completed.
Methods: We searched PUBMED, EMBASE, Cochrane Library, Web of Science (updated to November 7, 2018) and the associated references.
Background: Phenylephrine is the first-line vasoactive drug in the cesarean section under spinal anesthesia. The rate of hypotension remains high after intravenous preventive use of phenylephrine. However, few studies have investigated the effect of preventive intramuscular phenylephrine via a longer period of usage on fetal and maternal outcomes.

Methods: Several databases (PubMed, Embase, Web of Science and Cochrane Library) were searched from inception to April 2018 for trials comparing phenylephrine with ephedrine in cesarean delivery.
Objectives: This meta-analysis was conducted to compare the effects of goal-directed fluid therapy (GDFT) versus conventional fluid therapy (CFT) in colorectal surgery on patients' postoperative outcome and to detect whether the results differ between studies with the Enhanced Recovery After Surgery (ERAS) protocol and those without, between studies using different devices for GDFT, or between different surgical approaches (laparoscopy or laparotomy).
Methods: The Cochrane Library, PubMed, Embase, Wanfang Data and ClinicalTrials.com were searched for studies from January,1990 to February, 2018.
Aim: Recently, several randomized controlled trials (RCT) reported the effect of chewing gum on gastrointestinal function after gynecological surgery; however, these results are inconsistent. The aim of this study was to systematically analyze the effect of chewing gum on postoperative gastrointestinal function and complications in women undergoing gynecological surgery.
Methods: Pumbed, Embase, Cochrane Library, Web of Science, Chinese Wanfang databases, China National Knowledge Infrastructure and http://clinicaltrials.
Unlabelled: Glial cell hyperactivity has been proposed to be responsible for chronic pain, however, the mechanisms remain unclear. Interleukin (IL)-18, released from glial cells, has been reported to be involved in neuropathic pain. In this study, we investigated the role of IL-18 in bone cancer pain.

The objective of this study was to determine the role of impaired baroreflex regulation by the nucleus tractus solitarii(NTS) in the occurrence of AD in a rat model.
Methods: T4 spinal cord transection animal model was used in this study, which included 40 Male rats Colorectal distension (CD) was performed to assess AD and compare the changes of BP, HR, and BRS, six weeks after operation.
Objective: The present study is to investigate the analgesic roles of L-THP in rats with bone cancer pain caused by tumor cell implantation (TCI).
Methods: Thermal hyperalgesia and mechanical allodynia were measured at different time points before and after operation. L-THP (20, 40, and 60 mg/kg) were administrated intragastrically at early phase of postoperation (before pain appearance) and later phase of postoperation (after pain appearance), respectively.
Purpose: Epidural/spinal opioids are increasingly used to relieve parturients' pain in labour. Some studies indicate that opioids can induce side effects in neonates, such as respiratory depression and neurobehavioural changes. This meta-analysis aimed to clarify the effects of opioids in labour analgesia on neonates.
