Randomized Controlled Trial Comparative Study Clinical TrialInhalational anesthetic technique in microlaryngeal surgery: a comparison between sevoflurane-remifentanil and sevoflurane-alfentanil anesthesia.
We studied the effects of sevoflurane, remifentanil hydrochloride, and alfentanil anesthesia in terms of the hemodynamic responses and emergence characteristics of patients scheduled for elective microlaryngeal surgery. Sixty patients (ASA I to III) were randomly allocated into 2 groups: group S-R (sevoflurane-remifentanil) and group S-A (sevoflurane-alfentanil; 1:20 and 1:4 ratios of remifentanil to alfentanil for induction and maintenance of anesthesia, respectively; doses not strictly equipotent). The mean arterial pressure and heart rate were measured before and after induction of anesthesia, 1 and 3 minutes after endotracheal intubation, at the insertion of the operating laryngoscope, and every 3 minutes during surgery. ⋯ The emergence times and postoperative side effects did not differ, except for the greater pain score (p < .05) in group S-R. In conclusion, sevoflurane with remifentanil seems to maintain cardiovascular stability during microlaryngeal surgery more effectively than sevoflurane with alfentanil. Both anesthetic regimens seem to provide rapid and uneventful emergence.

Case ReportsHazardous foreign bodies: complications and management of button batteries in nose.
Miniature batteries are easily available in our domestic environment, powering many electronic devices and toys. Despite improvement in the safety standards, children are able to remove the batteries from these devices. These batteries pose a hazard to children, as they are small and easily inserted into the nose or ears or even swallowed. ⋯ Four of these insertions resulted in septal perforations. The mechanisms and management of button battery injury are discussed. We emphasize the need for urgent removal of a battery from the nose to prevent long-term complications.
