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.

Mixing of various adjuvants has been tried with local anesthetics in an attempt to prolong anesthesia from peripheral nerve blocks but have met with inconclusive success. More recent studies indicate that 8 mg dexamethasone added to perineural local anesthetic injections augment the duration of peripheral nerve block analgesia. ⋯ Addition of dexamethasone (8 mg) to ropivacaine in supraclavicular brachial plexus approach significantly and safely prolongs motor blockade and postoperative analgesia (sensory) that lasted much longer than that produced by local anesthetic alone.

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.

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.

The favorable kinetic properties of sevoflurane could be advantageous in obese patients undergoing bariatric surgery, improving recovery from general anesthesia (GA). ⋯ Sevoflurane has a better recovery profile based on eye opening, obeying commands, time for extubation and orientation, than isoflurane in morbidly obese patients undergoing laparoscopic sleeve gastrectomy.
