A randomized trial comparing two laryngeal mask airway insertion techniques.

This study was undertaken to compare laryngoscopic-guided LMA insertion with a standard insertion technique. A total of 149 patients undergoing elective general surgical and orthopaedic procedures were randomly divided into two groups. Study endpoints included ease of insertion, haemodynamic changes, local trauma bleeding, and postoperative sore throat. There were no statistically significant differences found. The laryngoscope may aid laryngeal mask airway insertion in some circumstances.

Use of EMLA cream or alfentanil for analgesia during ophthalmic nerve blocks.

This prospective double-blind study compared the effectiveness of EMLA with alfentanil and placebo in reducing the overall pain during ophthalmic nerve blocks. Seventy-five patients scheduled for cataract surgery were divided into three groups. Patients in the EMLA group had EMLA cream applied over skin areas corresponding to injection sites for retrobulbar and facial nerve blocks one hour before the nerve blocks, and placebo intravenous normal-saline injection 2 minutes before the first nerve block. The alfentanil group had placebo cream applied and intravenous alfentanil 10 micrograms.kg-1 while patients in the placebo group received placebo cream and intravenous normal-saline at similar time intervals prior to the nerve blocks. Patients then received facial nerve blocks and retrobulbar block by the same surgeon. Pain scores by patients and independent observers were significantly lower in the EMLA and alfentanil groups compared to placebo (P < 0.005) with no significant difference between the EMLA and alfentanil groups.
