Randomized Controlled Trial
Effect of intravenous lidocaine on short-term pain after hysteroscopy: a randomized clinical trial.
The role of intravenous lidocaine infusion in endoscopic surgery has been previously evaluated for pain relief and recovery. Recently, it has been shown to reduce postoperative pain and opioid in patients undergoing endoscopic submucosal dissection. Similar to endoscopic submucosal dissection, operative hysteroscopy is also an endoscopic surgical procedure within natural lumens. The present study was a randomized clinical trial in which we evaluated whether intravenous lidocaine infusion would reduce postoperative pain in patients undergoing hysteroscopic surgery. ⋯ Intravenous lidocaine infusion as an adjuvant reduces short-term postoperative pain in patients undergoing operative hysteroscopy.

Randomized Controlled Trial
Quadratus lumborum block (transmuscular approach) versus transversus abdominis plane block (unilateral subcostal approach) for perioperative analgesia in patients undergoing open nephrectomy: a randomized, double-blinded, controlled trial.
Patients undergoing open nephrectomy surgery experience severe perioperative pain, which is primarily due to incision of several muscles. Abdominal wall blocks are known to reduce pain without causing epidural-associated hypotension. We conducted this study to compare unilateral ultrasound-guided transmuscular quadratus lumborum block and posterior transversus abdominis block in combination with general anesthesia alone in terms of intraoperative and postoperative analgesics and hemodynamics and postoperative complications. ⋯ Transmuscular quadratus lumborum block and posterior transversus abdominis blocks were effective in providing perioperative analgesia in patients undergoing open nephrectomy. However, quadratus lumborum block provided superior analgesia.

Percutaneous dilation tracheostomy is an aerosol-generating procedure carrying a documented infectious risk during respiratory virus pandemics. For this reason, during the COVID-19 outbreak, surgical tracheostomy was preferred to the percutaneous one, despite the technique related complications increased risk. ⋯ This newly described percutaneous dilation tracheostomy technique was not related to severe desaturation events and we did not observe any positive serological test in health workers who performed the tracheostomies.

Both predictions and predictors of difficult laryngoscopy are controversial. Machine learning is an excellent alternative method for predicting difficult laryngoscopy. This study aimed to develop and validate practical predictive models for difficult laryngoscopy through machine learning. ⋯ Predicting difficult laryngoscopy is possible with three parameters. Severe damage resulting from failure to predict difficult laryngoscopy with high recall is small with the reported model. The model's performance can be further enhanced by additional data training.

Multimodal analgesia (MMA) is the current standard practice to provide post-cesarean analgesia. The aim of this study was to compare the analgesic efficacy of quadratus lumborum (QL) block and transversus abdominis plane (TAP) block as an adjunct to MMA. ⋯ Our study showed the significant delay in time to first analgesic request in QL group patients. Patients in the QL group had lower pain scores, required fewer analgesic supplements, and had more satisfaction. Nausea-vomiting and sedation were comparable.
