Objectives: Heart transplant is the most effective treatment in patients with advanced heart failure who are refractory to medical treatment. The brain death interval and type of inotrope We assessed the effects of these parameters on heart transplant outcomes.

Materials And Methods: In this follow-up study, we followed heart transplant recipients for 1 year to study patient survival, ejection fraction, adverse events, and organ rejection.

Article Synopsis
  • A tourniquet is commonly used during surgery to control bleeding but can cause severe pain, especially due to the nerve innervation in the inner arm.
  • This study involved 60 patients divided into three groups to compare the effectiveness of traditional ICBN block versus ultrasound-guided ICBN block on reducing tourniquet pain.
  • Both ICBN block methods significantly reduced pain compared to the control group, but there was no notable difference in effectiveness between the two techniques, with ultrasound guidance being recommended for increased success and safety.

Article Synopsis
  • - The study evaluated the effectiveness of the muscle relaxant atracurium for laryngeal mask airway (LMA) insertion in children undergoing surgery, comparing it to a saline control group.
  • - Out of 60 children, LMA insertion was similarly straightforward in both groups, with 66.7% in the atracurium group and 63.3% in the saline group having no significant difference in ease of placement.
  • - The results indicated that atracurium did not significantly improve LMA insertion or reduce complications like laryngospasm compared to saline, implying its limited effectiveness in this context.

Article Synopsis
  • This study compared the effectiveness of the laryngeal mask airway (LMA) with the endotracheal tube (ETT) in patients undergoing plastic and reconstructive surgeries under general anesthesia.
  • Conducted in 2020 at Hazrat Fatemeh Hospital in Tehran, the randomized trial included 80 patients and assessed various factors like ease of placement, oxygen saturation, and complications.
  • The findings suggested that LMA is a viable option for airway management during surgeries lasting over 2 hours, with no significant differences in key health metrics between LMA and ETT groups.

Article Synopsis
  • The study addresses the challenges anesthesiologists face when managing airways in obese patients, whose body composition can complicate intubation.
  • It compares a standard ramp position to a new low-cost modified ramp position for intubation during bariatric surgery, utilizing various metrics like laryngoscopic view and intubation duration.
  • Results indicate no significant differences in effectiveness between the two positions, suggesting the modified ramp is a viable, easier, and cheaper alternative.

Background: Earlier studies have suggested the liberal administration of fluids in favor of reducing the risk of rhabdomyolysis in obese patients, but the results are conflicting.

Objectives: The present study aimed at comparing the effects of liberal and restrictive fluid therapy on renal indices in laparoscopic gastric bypass surgery.

Methods: In a double-blinded randomized clinical trial, 72 candidates of bariatric surgery were randomly assigned into two groups of restrictive and liberal fluid therapy.

Background: Studies have reported lower pain threshold, spinal anesthesia duration, and level of sensory block in addicts compared to non-addict patients undergoing spinal anesthesia for surgery. Moreover, blood gas and cerebrospinal fluid (CSF) were likely to be affected as well. The aim in the present study is to evaluate CSF and spinal parameters in addict versus non-addict patients during lower limb surgery.

Backgrounds And Objective: Some studies have shown that deeper anesthesia is more effective on postoperative analgesia and reduces the need for sedative drugs. This study sought to investigate the effect of depth of anesthesia on postoperative pain in laparoscopic cholecystectomy.

Materials And Methods: In this double-blind clinical trial, 60 patients undergoing laparoscopic cholecystectomy were randomly divided into two groups: low bispectral index (L-BIS=35-44) and high bispectral index (H-BIS=45-55).

Background: To investigate antibiotic resistance, the occurrence and distribution of class 1 and 2 integrons in multidrug- resistant Staphylococcus aureus isolates from hospitals in Tehran, Iran. The isolates were examined for susceptibility to antimicrobial agents. The mecA gene, class 1 and 2 integrons were detected by PCR.

Background: Endotracheal Tube Cuff Pressure (ETCP) should be kept in the range of 20 - 30 cm H2O. Earlier studies suggested that ETCP assessment by palpation of pilot balloon results in overinflation or underinflation and subsequent complications such as tracheal wall damage and aspiration.

Objectives: The current study aimed to evaluate the effect of an in vitro educational program on the ability of anesthesia personnel to inflate Endotracheal Tube Cuffs (ETT) within safe pressure limits.

Article Synopsis
  • * A review of 52 studies from 1966 to 2013 confirmed that all halogenated anesthetics, like halothane and enflurane, can cause liver damage, particularly through a metabolic pathway involving cytochrome P-450 2E1, while sevoflurane appears to have a lower risk.
  • * Although liver toxicity from these anesthetics is not common, it is essential to acknowledge the potential link, especially with older agents like halothane compared to newer ones with lower hepatotoxicity.

Anesthesia personnel are at risk for needlestick injuries (NSIs). This study evaluated the knowledge of, attitudes toward, and practice of preventing NSIs among anesthesia personnel in four Iranian university hospitals. A self-administered anonymous questionnaire was distributed to 104 anesthesia personnel.
