Randomized Controlled Trial Clinical Trial[Efficacy of topical administration of lidocaine through a Malinckrodt Hi-Lo Jet tube in lessening cough during recovery from general anesthesia].
To achieve tracheal anesthesia during intubation, an endotracheal tube was purposely designed. The tube had multiple laser-induced perforations in its lower portion produced that allowed administration of the local anesthetic in a pulverized form. We evaluated the efficacy of lidocaine 2% in preventing cough during recovery from general anesthesia. ⋯ At the end of the anesthesia period, the presence of cough was treated with the test solution. In 90% of cases treated with lidocaine, cough disappeared in about 30 seconds and patients tolerated the endotracheal tube until extubation was performed. All patients who received saline solution presented cough until extubation.

Case Reports[Prophylaxis with dantrolene sodium in 2 patients with susceptibility to malignant hyperthermia].
We report 2 patients programmed for elective surgery who were considered susceptible to develop the malignant hyperthermia syndrome. The first patient had two familiarly antecedents of death produced by postanesthetic malignant hyperthermia, whereas the second patient suffered a clinical picture compatible with this syndrome during tonsillectomy, although followed a favourable recovery. The preoperative study including measurement of muscular enzymes, isoenzymes, and muscular biopsy was normal. ⋯ The second patient had a maxillary fracture which was treated with osteosynthesis under general anesthesia. During the intervention and the postoperative follow-up, both patients were free of signs related to malignant hyperthermia. We conclude that prophylaxis with dantrolene is necessary in patients susceptible to develop the syndrome of malignant hyperthermia.
