A 15 ml.kg(-1) of apple juice for patients of <3 years of age or 10 ml.kg(-1) for older children, at 06:00-06:30 am of the surgical morning is a simple procedure to prevent dehydration and to produce positive behavior in low-risk, pediatric surgical patients.
In patients undergoing hip surgery under regional anesthesia with bupivacaine, epidural morphine at a dose of 11.2 microg.kg(-1) administered immediately after completion of the procedure resulted in adequate pain relief for more than 12 h. Explanation of the high rate of patients vomiting (>45%) remains to be elucidated.
Ketorolac is a potent analgesic drug that has been restricted in dosage and use because of its potential adverse effects. The diagnostic and ethical challenges of 2 children who had unpredictable adverse drug reactions to ketorolac are reported. Case 1: A 3-year-old boy received ketorolac 1 mg/kg for prevention of postoperative pain at the end of an orthopedic surgical procedure. Ten minutes later, he had bilateral palpebral edema, erythema in thorax, hypotension, and tachycardia. The adverse event was classified as a mixed reaction probably related to ketorolac. Case 2: A 7-year-old girl, who had previously received ketorolac in 2 different surgical procedures, underwent a third orthopedic surgery. She received ketorolac 1 mg/kg as pre-emptive analgesia at 1.5 hours of anesthetic time (approximately 1 hour of surgical time). The patient developed palpebral edema 5 minutes later in addition to erythema in thorax, hypotension, tachycardia, tachypnea, oxygen desaturation, and wheezing. The adverse event was classified as a systemic reaction probably related to ketorolac. The 2 patients were successfully treated with symptomatic therapy. Although rare in its frequency, ketorolac administration may be associated to anaphylactic and anaphylactoid reactions in children with or without history of previous exposure. Because ketorolac is off-licensed for pediatric patients, it should be administered only after the risks and benefits have been discussed with the child's parents in the preanesthetic consultation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
