Stress-induced neuroendocrine and metabolic changes lead to intraoperative hyperglycemia which is related to surgery and the type of intravenous fluids used. ⋯ Nondiabetic patients undergoing major abdominal surgeries who received acetate-based fluids had relatively higher intraoperative blood sugar levels as compared to those receiving lactated solutions, but the incidence of hyperglycemia was comparable. When the duration of surgery exceeded 6 h, acetate-based solutions resulted in significantly higher lactate levels with progressive metabolic acidosis.

Vitamin D is associated with musculoskeletal function in our body, and its deficiency is a common health problem all over the world. Low back pain (LBP) is an important health problem in terms of low quality of life, loss of work power, and cost of diagnosis and treatment approaches. ⋯ The deficiency of Vitamin D is often asymptomatic, and also, it can cause bone and muscle pain. In our study, we determined that the severity of pain increased in patients with LBP as the deficiency of Vitamin D increased. For this reason, we recommend to be evaluated the level of Vitamin D in patients with LBP.

Apneic mass movement of oxygen by applying continuous positive airway pressure (CPAP) is possible only when the airway is kept patent which helps to reduce the rate of desaturation. ⋯ Preoxygenation with CPAP of 5 cmH2O followed by apneic oxygenation with CPAP keeping the airway patent with an oropharyngeal airway results in significantly higher PaO2 after preoxygenation and slower reduction in PaO2 during apnea.

Surgery is a very stressful experience for patients. Children are the most susceptible to fear, anxiety, and stress due to their limited cognitive capabilities and dependency. In children, pharmacologic agents are frequently used as premedication to relieve the fear of surgery, to make child-parental separation easy, and to carry out a smooth induction of anesthesia. We conducted this study to compare the efficacy of intranasal fentanyl, midazolam, and dexmedetomidine as premedication in pediatric patients. ⋯ Onset of action of fentanyl and midazolam is early as compared to that of dexmedetomidine. However, fentanyl provided better conditions for induction and emergence than midazolam. With dexmedetomidine onset of action was delayed and duration of action was prolonged which helped child to remain calm and sedated even after the surgery.

Abdominal hysterectomy is associated with sever postoperative pain. Quadratus lumborum (QL) block is a regional analgesic technique which has an evolving role in postoperative analgesia. ⋯ Bilateral QL block provided better intraoperative and postoperative analgesia with less opioids consumption compared with bilateral TAP block, in patients undergoing total abdominal hysterectomy.
