Randomized Controlled Trial Clinical TrialIntravenous ketorolac tromethamine versus meperidine for adjunctive sedation in upper gastrointestinal endoscopy: a pilot study.
Meperidine is commonly used with a benzodiazepine to achieve conscious sedation but may potentiate respiratory depression. Ketorolac tromethamine has few sedative effects and no respiratory depression. The purpose of this study was to compare ketorolac to meperidine as adjuncts in conscious sedation for upper gastrointestinal endoscopy (EDG). ⋯ There is no benefit to ketorolac as an adjunct in conscious sedation for EGD. Meperidine had several benefits; however, discomfort at the intravenous site was common.

Comparative StudyProspective comparison of helium versus carbon dioxide pneumoperitoneum.
During prolonged laparoscopic operations with carbon dioxide (CO2) pneumoperitoneum (PP), hypercapnia with significant acidosis has been reported to occur in some patients with pulmonary dysfunction. An alternate inert insufflation gas like helium (He) could avoid this problem. ⋯ He PP is an effective alternative to CO2 PP for a laparoscopic cholecystectomy avoiding CO2 retention and subsequent acidosis. Carbon dioxide retention may be dangerous in patients with pulmonary dysfunction who undergo laparoscopy.
