Anesthesia, essays and researches

A well-secured endotracheal tube (ETT) is essential for safe anesthesia. The ETT has to be fixed with the adhesive plasters or with tie along with adhesive plasters appropriately. It is specially required in patients having beard, in intensive care unit (ICU) patients or in oral surgeries. ⋯ We report an incidence where the ETT cuff tubing was severed while attempting to re-adjust and re-fix the ETT and the patient required re-intubation. Retrospectively, we thought of and describe a safe, reliable and novel technique to prevent cuff deflation of the severed inflation tube. The technique can also be used to monitor cuff pressure in such scenarios.

Hypothermia is a frequent observation in elderly males undergoing transurethral resection of prostate (TURP) under spinal anesthesia. The use of irrigating fluids at room temperature results in a decrease body temperature. Warmed irrigating solutions have shown to reduce heat loss and the resultant shivering. Such investigation was not much tried in low resource settings. ⋯ Use of warm irrigation fluid during TURP reduces the risk of perioperative hypothermia and shivering.

Anesthetists used lower doses of fentanyl, successfully with hemodynamic control by titrating volatile anesthetic agents or vasodilators for fast-tracking in cardiac surgery. ⋯ The I-gel airway is well-tolerated by adult patients undergoing cardiac surgery, and requires lower total doses of anesthetics than endotracheal intubation with hemodynamic control and helps in fast-tracking.

For optimum magnetic resonance imaging (MRI) image quality and to ensure precise diagnosis, patients have to remain motionless. We studied the effects of intranasal dexmedetomidine and ketamine with intravenous midazolam for pre-procedural and procedural sedation in school aged children. ⋯ Intranasal dexmedetomidine 3 μg kg(-1) or ketamine 7 mg kg(-1) can be used safely and effectively to induce a state of moderate conscious sedation and to facilitate parents' separation and IV cannulation. Addition of midazolam in a dose not sufficient alone to produce the target sedation achieved our goal of deep level of sedation suitable for MRI procedure.

A double-blinded randomized controlled study to compare discharge time and patient satisfaction between two groups of patients submitted to open surgeries for abdominal malignancies using segmental thoracic spinal or general anesthesia. ⋯ This preliminary study has shown that segmental thoracic spinal anesthesia can be used successfully and effectively for open surgeries for abdominal malignancies by experienced anesthetists. It showed shorter postanesthesia care unit stay, better postoperative pain relief and patient satisfaction than general anesthesia.
