Randomized Controlled Trial
Comparison of different end-tidal carbon dioxide levels in preventing postoperative nausea and vomiting in gynaecological patients undergoing laparoscopic surgery.
The aim of this study was to compare different end-tidal carbon dioxide (EtCO2) levels to prevent postoperative nausea and vomiting (PONV) caused by increased intracranial pressure due to pneumoperitoneum and Trendelenburg position in gynaecological laparoscopic surgery. A total of 60 female patients aged 25-50 years who would undergo laparoscopic gynaecological surgery under general anaesthesia were randomised into two groups: group A (EtCO2: 26 - 35 mmHg, n = 30) and group B (EtCO2: 36 - 45 mmHg, n = 30). In both groups, ONSD and EtCO2 of the patients were measured at baseline after anaesthesia induction (Tb), at 5 min after pneumoperitoneum (TPP5), and at 10 min intervals after Trendelenburg position (TPP10, TPP20, TPP30). ⋯ What the results of this study add? Postoperative nausea and vomiting caused by intracranial pressure (ICP) increase due to carbon dioxide pneumoperitoneum and Trendelenburg position in gynaecologic laparoscopic surgeries were decreased in the early postoperative period by low end-tidal carbon dioxide levels in the intraoperative period. It was shown that low end-tidal carbon dioxide levels have beneficial effects on ICP and PONV in laparoscopic gynaecologic operations. What the implications are of these findings for clinical practice and/or further research? This result indicates that low end-tidal carbon dioxide levels have beneficial effects on ICP and PONV in laparoscopic gynaecologic operations.

Randomized Controlled Trial
Effect of elastic abdominal binder on pain and functional recovery after caesarean delivery: a randomised controlled trial.
The Elastic abdominal binder has been widely employed by clinicians for pain relief, wound complications prevention, improved pulmonary function, and stabilisation. However, these proposed benefits have not been properly examined in women following caesarean delivery. We aimed to examine the effects of post-caesarean elastic abdominal binder use on recovery by comparing post-operative pain, mobility and quality of life. ⋯ What do the results of this study add? In contrast to the results of the previous study, the beneficial effects of abdominal binder on pain reduction, functional recovery, and quality of life following caesarean delivery could not be demonstrated in this study. What are the implications of these findings for clinical practice and/or further research? The use of elastic abdominal binder after caesarean delivery is not associated with reduction of postoperative pain, faster functional recovery, and improved quality of life in our population. Further studies in other population with different characteristics may be worthwhile.

Randomized Controlled Trial
Clinical observation of regular intermittent epidural injection combined with different puncture points in suppressing breakthrough pain in labour analgesia.
The aim of the current study was to evaluate the clinical effects of the regular intermittent epidural injection combined with different puncture points (RIEI-dPP) in suppressing breakthrough pain during a labour analgesia. A total of 90 primipara were randomly divided into three groups (n = 30): Group L2-3 (A), Group L3-4 (B) and Group L4-5 (C). The analgesic pump parameters were set as: impact dose 8 mL, locking time 15 minutes, background dose 0, and the additional impact dose 8 mL after each hour intermittence. ⋯ What the implications are of these findings for clinical practice and/or further research? Compared with a continuous infusion, a regular intermittent epidural injection can achieve a more uniform drug distribution in the epidural space, so the block range can be more extensive, which can not only reduce the amount of anaesthetic but also effectively reduce the incidence of breakthrough pain. However, the selection of an intervertebral puncture site still lacks a uniform standard. The outcomes of this study can directly verify that regular intermittent epidural injection at L2-3, L3-4 and L4-5 can effectively inhibit breakthrough pain and achieve good analgesic effects, so selecting the intervertebral space with clear anatomical structure positioning and easier puncture pathway can benefit a labour analgesia.

Randomized Controlled Trial
Oral paracetamol premedication effect on maternal pain in amniocentesis: a randomised double blind placebo-controlled trial.
The objective of this study was to evaluate the effectiveness of oral paracetamol premedication in decreasing the maternal pain during amniocentesis. A randomised double blind placebo-controlled trial was conducted. Two hundred and forty participants were equally allocated into two groups (one paracetamol and one placebo). ⋯ What the results of this study add? Paracetamol is effective in decreasing the maternal pain during and after amniocentesis. What the implications are of these findings for clinical practice and/or further research? Pregnant women who need amniocentesis should be counselled that paracetamol could be administered for relieving the pain that may occur from the procedure. However, further study should be conducted to find the optimal dosage of paracetamol for relieving the pain in amniocentesis along with a large RCT with a long-term follow-up to evaluate the side effects of paracetamol.

Randomized Controlled Trial
Bolus administration of intravenous lidocaine reduces pain after an elective caesarean section: Findings from a randomised, double-blind, placebo-controlled trial.
We conducted a randomised double-blind, placebo-controlled trial to assess whether a bolus dose of lidocaine during the induction of general anaesthesia would reduce postoperative pain over 24 h. Level of satisfaction with pain control at 48 h after surgery and Apgar score were also examined. A total of 100 women aged 20-35 years, who were candidates for elective caesarean section (CS) were randomised to receive either 1.5 mg/kg lidocaine or placebo during the induction of general anaesthesia. ⋯ In this randomized, placebo-controlled trial the use of a bolus dose of 1.5 mg/kg lidocaine 2%, compared with placebo, during the induction of general anaesthesia for elective CS resulted in a significant decrease in postoperative pain score as well as decreased postoperative morphine consumption over 24 h. Lidocaine use was not associated with any side effect in participants and newborns. • This study provides the first evidence that a bolus dose of lidocaine may be a safe and simple alternative therapeutic intervention for enhanced postoperative recovery in terms of pain and postoperative opioid consumption. Future studies are needed to examine pain reducing effect of perioperative bolus dose of lidocaine after CS under spinal or epidural anesthesia.
