Randomized Controlled Trial Clinical Trial
Efficacy of bronchodilators in the treatment of bronchiolitis.
Bronchiolitis is a common respiratory infection affecting young children. Much controversy revolves around the efficacy of bronchodilators in the treatment of bronchiolitis. This study was conducted to address this issue. ⋯ The use of bronchodilators did not alter the course of the disease and is therefore not effective in the treatment of bronchiolitis.

Combination of suppository diclofenac and intravenous morphine infusion in post-caesarean section pain relief--a step towards balanced analgesia?
Post-Caesarean section analgesia can be achieved by morphine infusion. NSAIDs are frequently administered to relieve uterine cramps. This study is aimed at assessing the efficacy of the combination of suppository diclofenac and morphine infusion in post-Caesarean section pain relief. General anaesthesia was given to 60 patients who were randomly allocated into two groups: group A received 100 mg suppository diclofenac before surgical incision and morphine infusion 1.5 mg per hour postoperatively while group B received only morphine infusion 1.5 mg/H postoperatively. Pain assessment was done by an unbiased observer on arrival of the patients in the recovery room, then 6 hours, 12 hours and 24 hours later. Pain relief was found to be better in group A, with group B requiring more supplemental analgesia. Apart from better analgesic effect for wound pain, group A also had more favourable scores for uterine cramping pain. The incidence of nausea or vomiting was similar in both groups. No respiratory depression was observed in both groups. Two cases of increased bleeding (one from each group) were observed, both receiving conservative treatment. ⋯ suppository diclofenac improved the analgesic efficacy of morphine infusion in post-Caesarean analgesia.

Randomized Controlled Trial Comparative Study Clinical Trial
Oral premedications in paediatric day surgery.
The degree of sedation in 191 day-stay children after oral premedication were compared. One hundred and forty-six were 1-5 years old (Group 1) and were randomised to receive either chloral 40 mg/kg, midazolam 0.2 mg/kg, promethazine 1 mg/kg, trimeprazine 3 mg/kg or placebo. Forty-five were 5-12 years old and were randomised to receive either trimeprazine 3 mg/kg, midazolam 0.2 mg/kg or placebo (Group 2). ⋯ They were assessed on leaving the ward, at separation from the parents, at induction, in the recovery room and one and two hours after returning to the ward. In Group 1, it was found that chloral and trimeprazine gave the best degree of sedation but the sedative effect of trimeprazine lasted longer into the post operative period. In Group 2, it was found that the children did not require deep sedation and the anxiolysis obtained with midazolam was adequate.

Randomized Controlled Trial Clinical Trial
Intra-articular morphine and bupivacaine for pain relief after therapeutic arthroscopic knee surgery.
This randomised, double-blind study compared the analgesic properties of intra-articular injection of morphine and bupivacaine during therapeutic arthroscopic knee surgery. Forty male patients were randomly divided into 4 groups of 10 patients each. Group A received intra-articular injection of 1 mg morphine sulphate in 20 ml saline, Group B received 20 ml of 0.25% bupivacaine while Group C received 1 mg morphine sulphate in 20 ml of 0.25% bupivacaine injected intra-articularly. ⋯ At 4 hours, it showed similar analgesic efficacy as morphine. There was no significant analgesic effect at the end of the study period. The combination of the two drugs resulted in satisfactory analgesia throughout the entire study period (p < 0.001 at 1, 2 and 24 hours and p < 0.05 at 4 hours) and appeared to be a simple, safe and effective analgesic technique for patients who underwent therapeutic arthroscopic knee surgery.

Randomized Controlled Trial Comparative Study Clinical Trial
Topical nasal anaesthesia for fibreoptic bronchoscopy: lignocaine spray or gel?
Lignocaine spray for anaesthetising the nasal mucosa for fibreoptic bronchoscopy often causes discomfort to the patient. We compared two techniques of applying nasal topical anaesthesia using either lignocaine spray (group A: 25 patients) or gel (group B: 30 patients) to assess patients' tolerance to the procedure. Both groups received 100 mg of lignocaine in the nostril, 40-50 mg to oropharynx, 120 mg to vocal cords and 40-100 mg to trachea and bronchi. ⋯ Significantly more patients in group A experienced discomfort or pain during nasal anaesthesia as compared to group B (p < 0.001). Patients' tolerance to the bronchoscopy was similar in both groups and the examination was performed satisfactorily in all patients. Thus, lignocaine gel is a simple technique, effective and less irritating as compared to lignocaine spray for topical nasal anaesthesia.
