AI Article Synopsis
- Shivering is a common side effect after C-sections with spinal or epidural anesthesia, yet it often goes untreated.
- A clinical trial with 80 women assessed the effectiveness of intravenous dexmedetomidine (DEX) against a control of normal saline in preventing shivering during elective C-sections.
- Results showed that DEX significantly reduced both the incidence and severity of shivering, improved sedation levels, and didn't cause major side effects compared to the control group.
Article Abstract
Background: Shivering is one of the most common side effects after cesarean section (C-section) under spinal or epidural anesthesia. However, it is often not treated.
Objectives: The aim of this study was to evaluate the effectiveness of intravenous dexmedetomidine (DEX) in the prevention of shivering after intrathecal anesthesia in women undergoing C-sections.
Methods: This double-blind, placebo-controlled clinical trial was conducted on 80 women candidates for elective C-sections under intrathecal anesthesia who were referred to Imam Khomeini Governmental Hospital in Ahvaz, Iran, during 2020 - 2021. Patients were randomly divided into two groups of intravenous DEX (group D; 0.5 µg/kg) and normal saline (control, group C) and received the medications after umbilical cord clamping. All patients were evaluated during and after surgery for hemodynamic changes, the incidence and severity of shivering based on Chu and Tsai, side effects (e.g., nausea, vomiting), and sedation level based on the Ramsey scale.
Results: The incidence of shivering in group C was significantly higher than in group D (P = 0.003). Moreover, the severity of shivering on minutes 20, 30, and 45 in group C was significantly higher than in group D (P < 0.05). The mean sedation score during minutes 10 - 30 in group D was significantly higher than in group C (P < 0.05). Heart rate was not significantly different between the two groups (P < 0.05). Systolic and diastolic blood pressure were higher in group D than in group C (P < 0.05).
Conclusions: The administration of intravenous DEX effectively reduces the incidence and severity of shivering and provides appropriate sedation in patients undergoing C-sections, and it does not cause remarkable side effects.

Background: For decades, poor treatment options and low-quality evidence plagued care for patients with rifampin-resistant tuberculosis. The advent of new drugs to treat tuberculosis and enhanced funding now permit randomized, controlled trials of shortened-duration, all-oral treatments for rifampin-resistant tuberculosis.
Methods: We conducted a phase 3, multinational, open-label, randomized, controlled noninferiority trial to compare standard therapy for treatment of fluoroquinolone-susceptible, rifampin-resistant tuberculosis with five 9-month oral regimens that included various combinations of bedaquiline (B), delamanid (D), linezolid (L), levofloxacin (Lfx) or moxifloxacin (M), clofazimine (C), and pyrazinamide (Z).

Background And Aims: In cirrhosis, some patients display acute encephalopathy without hyperammonemia (NonHep E) which is not considered as overt hepatic encephalopathy (OHE). We aimed to assess the prevalence and characteristics of NonHep E and OHE in cirrhotic patients displaying acute encephalopathy, assess their respective prognosis and compare it to other causes of acute decompensation (AD) with/without hyperammonemia.
Approach And Results: We conducted a retrolective analysis from a prospective cohort of patients hospitalized for AD.
