Case ReportsCombination of ultrasound-guided lumbosacral plexus block with anterior quadratus lumborum block in supine position for hip surgery: a case report.
It was widely recognized that the procedure of ultrasound-guided lumbar and sacral plexus block is required to be performed in a lateral decubitus position that patients' hips and knees were bended. It is difficult, however, for patients with hip fractures to change position because of severe pain and confined movements. We here reported a new modified combination of ultrasound-guided lumbosacral plexus block with anterior quadratus lumborum block in supine position that had been successfully applied in one elderly patient who underwent hip surgery.

Usefulness of pre- and intraoperative risk scores in nonagenarian surgical patients.
Preoperative assessment at extreme ages would identify patients at a high risk of developing postoperative complications. The objective of this study was to compare the usefulness of different risk scales in a series of nonagenarian surgical patients. ⋯ As in the general population, the Surgical Apgar Score and SASA score are the best predictors of operative mortality and morbidity in nonagenarian patients. These risk scales should be considered in the perioperative management of these patients.

The aim of this study was to determine the effect of an aerosol box on tracheal intubation difficulty. Eighteen experienced anesthetists intubated the trachea of a manikin with a normal airway 6 times using a direct laryngoscope, a McGRATH™ MAC videolaryngoscope, or an airway scope AWS-S200NK videolaryngoscope with or without an aerosol box. ⋯ When using any of the laryngoscopes, there were no statistically significant differences in the Cormack-Lehane grade and peak force to maxillary incisors with and without the aerosol box. In summary, the effect of an aerosol box on tracheal intubation difficulty is not clinically relevant when an experienced anesthetist intubates the trachea in a normal airway condition.

Individual pharmacometric analysis for sugammadex reversal and re-administration of neuromuscular blockade.
Sugammadex is an innovative reversal agent for neuromuscular blockade (NMB) induced by rocuronium. Although there is a case that re-paralysis is necessary after sugammadex administration, limited reports can be found on the sugammadex dosage for reversal from profound paralysis after induction and immediate re-paralysis following such reversal in detail. We experienced a case in which NMB reversal was required in a short period after paralysis for induction due to the discovery of anisocoria. ⋯ In this case, the dose of approximately 8 mg/kg sugammadex but not the conventional dose of 16 mg/kg would be enough for immediate reversal after induction. For the re-paralysis 30 min after NMB reversal, not 1.4 mg/kg but 2.2 mg/kg rocuronium was an adequate dose. Taking individual differences including given dose and time intervals in consideration, NMB monitoring should be used to determine the necessary dose of rocuronium and sugammadex in such situations.
