INTRODUCTION: Tracheostomy is the most frequent bedside surgical procedure performed on patients with traumatic brain injury who require mechanical ventilation. To compare the effects of early tracheostomy vs late tracheostomy on the duration of mechanical ventilation in patients with traumatic brain injury, we carried out a systematic review and meta-analysis. EVIDENCE ACQUISITION: MEDLINE, Scopus, Web of Science, and Cochrane were searched from inception to 17th October 2022...

INTRODUCTION: This review and meta-analysis of randomized controlled trials (RCTs) assessed the side effects and efficacy of esketamine combined with propofol in procedural sedation and analgesia. EVIDENCE ACQUISITION: The PubMed, MEDLINE, Embase and Cochrane Library databases were searched for relevant studies occurring between their inceptions and September 2022. The primary outcome was the incidence of sedation-related adverse events. Secondary outcomes included recovery time, total consumption of propofol and body movement...

BACKGROUND: Extracorporeal carbon dioxide removal (ECCO<inf>2</inf>R) promotes protective ventilation in patients with acute respiratory failure, but devices with high CO<inf>2</inf> extraction capacity are required for clinically relevant impact. This study evaluates three novel low-flow techniques based on dialysate acidification, also combined with renal replacement therapy, and metabolic control. METHODS: Eight swine were connected to a low-flow (350 mL/min) extracorporeal circuit including a dialyzer with a closed-loop dialysate circuit, and two membrane lungs on blood (ML<inf>b</inf>) and dialysate (ML<inf>d</inf>), respectively...

BACKGROUND: Opioid sparing techniques have been shown to promote gastrointestinal recovery, shorten length of stay (LOS), and reduce opioid-related complications. We investigated whether intraoperative intravenous lidocaine or dexmedetomidine infusion could improve gastrointestinal recovery in elderly patients undergoing laparoscopic colorectal surgery. METHODS: Ninety-six patients aged 65 years or older who underwent elective laparoscopic colorectal resection were randomly allocated into the following three groups: the control group (N...

BACKGROUND: In adults undergoing noncardiac surgery, the correlation between intraoperative tidal volume and postoperative acute kidney injury (AKI) is unclear. This study aimed to investigate the effects of low tidal volume ventilation on the incidence of postoperative AKI compared with conventional tidal volume in adults undergoing noncardiac surgery. METHODS: This was a two-center prospective randomized controlled trial on adult patients who underwent noncardiac surgery and had a mechanical ventilation of >60 min...

BACKGROUND: The fluid challenge (FC) response is usually evaluated as binary, which may be inadequate to describe the complex interactions between heart function and vascular tone response after fluid administration. We applied a clustering approach to assess the different phenotypes of cardiovascular responses to FC administration, considering the associations of all the baseline variables potentially influencing pressure and flow response to a FC. Secondarily, we evaluated the reliability of baseline hemodynamic variables in discriminating fluid responsiveness, which is considered the standard approach at the bedside...

INTRODUCTION: Remimazolam is a novel sedative drug that has been successively approved for procedural sedation and general anesthesia, however, which has not been fully explored due to limited clinical studies and a small sample size. Current clinical studies have focused on the use of remimazolam and propofol for general anesthesia (GA) as indicators of safety outcomes in surgical patients, but different studies have reached different conclusions. The aim of this study was to investigate whether the safety-related outcome indicators in GA were superior to propofol in surgical patients...

INTRODUCTION: Genetic variants may affect drug efficacy on postoperative nausea and vomiting (PONV). The understanding of these mechanisms will help to identify the surgical patients who might benefit from specific prophylactic and therapeutic antiemetic treatment. The aim of the present review was to investigate gene polymorphisms that influence 5-hydroxytryptamine (serotonin) type 3 receptor antagonists (5HT3RA) efficacy in PONV. EVIDENCE AQUISITION: We included articles published from 2005 to 2022, utilizing the electronic databases PUBMED, EMBASE, COHRANE Library and ScienceDirect...

INTRODUCTION: Midazolam hydrochloride is a widely accepted benzodiazepine for premedication in pediatric patients. However, there is no consistent conclusion regarding which route of administration is best. We performed a meta-analysis to assess the efficacy and safety of oral versus intranasal midazolam premedication in children. EVIDENCE ACQUISITION: The PubMed, Embase, Cochrane Library, and Google Scholar databases were searched from inception to June 2022, for randomized controlled trials comparing oral versus intranasal midazolam...

BACKGROUND: The midline skin incision for total knee arthroplasty may be an important generator of chronic neuropathic pain. The incision is innervated by the medial femoral cutaneous nerve (MFCN), the intermediate femoral cutaneous nerves (IFCN) and the infrapatellar branch from the saphenous nerve. The MFCN divides into an anterior (MFCN-A) and a posterior branch (MFCN-P). The primary aim was to compare the areas anesthesized by MFCN-A versus MFCN-P block for coverage of the incision...

BACKGROUND: Ultrasound showed to improve the precision and efficacy of spinal anesthesia (SA) through the identification of specific structures surrounding the intrathecal space, such as the anterior and posterior complex of dura mater (DM). The aim of this study was to verify the efficacy of ultrasonography in predicting difficult SA trough the analysis of different ultrasound patterns. METHODS: This prospective single-blind observational study involved 100 patients undergoing orthopedic or urological surgery...
