This study was designed to compare the intra-operative and post-operative analgesic requirements and side effects of using fentanyl infusion versus remifentanil infusion during short-duration surgical procedures in children. The study comprised of 40 children randomly allocated into two equal groups: fentanyl (F-group) or remifentanil (R-group). Both were administered a continuous intravenous (i.v.) infusion. ⋯ Fentanyl provided significantly better PO analgesia than remifentanil and children in F-group showed a significantly lower mean cumulative OPS record than those in R-group; however, the number of patients requiring rescue analgesia did not show a significant difference between both the groups. Two cases in F-group and one in R-group had bradycardia, one case in R-group had mild hypotension and PO vomiting had occurred in three patients in the F-group and two patients in the R-group. In conclusion, remifentanil is appropriate for opioid-based anaesthesia for paediatric patients as it provides haemodynamic stability and rapid recovery with minimal post-operative side effects.

Non-cardiogenic pulmonary oedema (NCPE) is a clinical syndrome characterized by simultaneous presence of severe hypoxemia, bilateral alveolar infiltrates on chest radiograph, and no evidence of left atrial hypertension/congestive heart failure/fluid overload. The diagnosis of drug-related NCPE relies upon documented exclusion of other causes of NCPE like gastric aspiration, sepsis, trauma, negative pressure pulmonary oedema, etc. ⋯ Both patients were treated successfully with mechanical ventilatory support, and adjuvant therapy, viz., frusemide, dopamine, steroids. This report emphasizes that this fatal complication may be seen with neostigmine, the pathogenic mechanism remains unknown, and it probably is a drug-related NCPE.

For treatment of intra and postoperative pain, no drug has yet been identified that specifically inhibits nociception without associated side effects. Magnesium has antinociceptive effects in animal and human models of pain. The current prospective randomised double-blind study was undertaken to establish the effect of addition of magnesium or clonidine, as adjuvant, to epidural bupivacaine in lower abdominal and lower limb surgeries. ⋯ In group C there was prolongation of duration of anaesthesia and sedation with lower VAS score, but the incidence of shivering was higher. The groups were similar with respect to haemodynamic variables, nausea and vomiting. The current study establishes magnesium sulphate as a predictable and safe adjunct to epidural bupivacaine for rapid onset of anaesthesia and clonidine for prolonged duration of anaesthesia with sedation.

Endotracheal tube (ETT) should have intracuff pressure (ICP) in the range of 20 to 30 cm water (H(2)O). In this observational study, we studied the trend amongst anaesthesiologist in choosing the type of ETT and their ability to assess optimum ICP clinically. After institutional ethics committee approval, we observed 75 patients under general endotracheal anaesthesia in Government Medical College. ⋯ Red rubber ETT (reusable) with low-volume high-pressure cuff is still in use, though the trend is shifting towards more of using PVC ETT. Anaesthesiologists were not able to inflate the ETT cuff to the recommended range in spite of their clinical expertise (more than 5 years of teaching experience) in significant number of cases. We recommend the use of simple aneroid manometer for objective monitoring of ICP over subjective assessment, not only in red rubber, but also in PVC ETT.
