The role of magnesium as an adjuvant during general anaesthesia.

Magnesium sulphate is used extensively in the treatment of eclampsia, and is also used to treat refractory arrhythmias, asthma, myocardial ischaemia and acute respiratory failure. We studied the interaction between magnesium sulphate and the anaesthetic agents propofol, rocuronium bromide and fentanyl citrate. This randomised, double blind study was conducted in 50 patients. The magnesium group A (n = 25) received 30 mg x kg(-1) magnesium sulphate before induction of anaesthesia and 10 mg x kg(-1) continuously intra-operatively until the end of surgery. Group B (n = 25) received the same volume of isotonic saline. Propofol, rocuronium and fentanyl infusions were started and the patients lungs' were ventilated with 33% oxygen in nitrous oxide. Anaesthetic depth was maintained at a bispectral index value of between 40 and 60. Muscle relaxation was maintained at a train-of-four count of 1 throughout surgery using neuromuscular monitoring. The fentanyl infusion was titrated to haemodynamic variables: heart rate and blood pressure. We concluded that magnesium sulphate has anaesthetic, analgesic and muscle relaxation effects and significantly reduces the drug requirements of propofol, rocuronium and fentanyl during anaesthesia.

Guided tactile probing: a modified blind orotracheal intubation technique for the problem-oriented difficult airway.

We present 'tactile probing', a guided approach to blind orotracheal intubation to secure a problem-oriented anticipated difficult airway in a 55-year-old male patient scheduled for elective surgical tracheostomy for a postradiotherapy translaryngeal carcinoma. Standard techniques to gain the airway were inapplicable in this case and awake flexible fiberoscopy-aided intubation had already failed.

Extraperitoneal endoscopic groin hernia repair under epidural anesthesia.

We performed a prospective study to evaluate the feasibility of performing endoscopic total extraperitoneal repair of groin hernia (TEP) under epidural anesthesia in selected patients considered to be at high risk or unfit for general anesthesia. Fifty-eight endoscopic total extraperitoneal hernia repairs were performed in 36 patients between January 1997 and December 1999 under epidural anesthesia since they were considered a high risk or unfit for general anesthesia. All patients received intramuscular diclofenac sodium for preemptive analgesia. Intraoperatively, all were sedated with intravenous midazolam and fentanyl. Endoscopic TEP repair was successful under epidural anesthesia in 33 of 36 patients. In the remaining three patients, the procedure had to be converted to Lichtenstein's repair due to shoulder discomfort experienced by the patients as a result of pneumoperitoneum, which was produced by incidental peritoneal tears during extraperitoneal dissection. Intraoperatively, one patient had bleeding from the inferior epigastric artery, which was controlled with clipping of the artery. The mean operative time was 48 minutes (range, 28-72 minutes) in the TEP group and 94 minutes (range, 84-102 minutes) in the converted group. All the patients received an epidural top-up dose at the end of surgery for postoperative analgesia. All patients were ambulatory the same day. Postoperative pain was assessed by a visual analogue scale (VAS). The mean pain score was 1.2 (+/- 0.8) on discharge in the TEP group. During follow-up, seven patients developed scrotal swelling with cord induration, which was treated conservatively with scrotal support and analgesics. In all patients, resolution was observed within 6 weeks. One patient was detected to have a recurrence 4 months after surgery. Endoscopic TEP repair under epidural anesthesia appears to be safe, technically feasible, and an acceptable alternative in patients who are at high risk or unfit for general anesthesia.

Infantile pyoderma gangrenosum.

A six month old female infant with pyoderma gangrenosum is reported. Pyoderma gangrenosum in an infant is rare. The child responded to pulse therapy with intravenous dexamethasone and intralesional triamcinolone acetonide.

Penicillinase ELISA for detection of tubercular antigen in tuberculosis.

Stick sandwich enzyme linked immunosorbent assay (ELISA) using rabbit anti PPD-RT 23 immunoglobulins and enzyme penicillinase has been explored for detection of tubercular antigen in sera and CSF samples of pulmonary tuberculosis and tubercular meningitis (TBM) respectively. The analysis of sera showed 73.3% of pulmonary tuberculosis cases, 16.2% of healthy controls and 44.4% of Hansen's disease positive for tubercular antigen. The accuracies of positive and negative predictive values were 69% and 82% respectively. The analysis of CSF samples showed the presence of tubercular antigen in 76.4% of TBM, 16.6% of pyogenic meningitis cases, 19.4% of neurological diseases other than meningitis and 16.1% non-neurological disease controls. The accuracies of positive and negative predictive values were 48% and 94% respectively. Hence this simple test using economical and indigenous reagents can be applied for the diagnosis of pulmonary and extra-pulmonary tuberculosis.
