Muscle relaxation using neuromuscular blocking agent is an essential process for endotracheal intubation and surgery, and requires adequate recovery of muscle function after surgery. Residual neuromuscular blockade is defined as an insufficient neuromuscular recovery that can be prevented by confirming train-of-four ratio >0.9 using objective neuromuscular monitoring. Sugammadex, a novel selective relaxant-binding agent, produces rapid and effective reversal of rocuronium-induced neuromuscular blockade. We report a case of the residual neuromuscular blockade accompanying dyspnea and stridor after general anesthesia in an unrecognized pre-existing symptomless unilateral vocal cord paralysis patient, who had experienced the disappearance of dyspnea and stridor after administration of sugammadex.

We present an uncommon case of hypoesthesia in the posterior and upper third of the superior area on the left ear auricle, after arthroscopic surgery of the shoulder in the lateral position under general anesthesia with ultrasound guided-interscalene brachial plexus block. A 65-year-old man underwent arthroscopic rotator cuff repair of the left shoulder in the right lateral decubitus position. Two days after operation, he complained of numbness around the left auricle; his symptoms persisted until 6 weeks after surgery. Audiometry and sensory examinations were normal. He recovered naturally by 6 months postoperatively. Postoperative neurological deficits that may not be block-related can be attributed to a combination of factors, such as patient-, anesthesia-, and surgery-related factors, including direct trauma, positioning, and retraction. Anesthesiologists should be aware that the injury may not be block-related and consider other possible causes. Citations Citations to this article as recorded by

We analyzed retrospectively incidence, management, and predictors of difficult intubation, which have been known through practical cases. A total of 217 cases of difficult intubation (DI) between 2010 and 2014 were investigated. Risk factors such as age, body mass index, Mallampati score, thyromental distance, degree of mouth opening and range of neck motion, Cormack-Lehane grade, intubation and airway management techniques were investigated. The cases of each department were analyzed and the airway management techniques according to simplified risk scores (SRS) were also investigated. The average incidence of DI was 0.49%. Patients undergoing surgery in the departments of oro-maxillo-facial surgery (1.35%), ophthalmologic surgery (0.96%), urologic surgery (0.80%), and head and neck surgery of ear-nose-throat (0.62%) showed the higher incidence of DI. Difficult mask ventilation (10 of 217, 4.6%) was occurred with DI. Higher SRS were related to high rates of video laryngoscope use and fiberoptic guided intubation. There was a decrease in the use of McCoy blades after 2013, an increase in the use of video laryngoscope, and a consistent rate of fiberoptic intubation. It is not easy to check all the predictors of DI in a preanesthetic evaluation and the predictors are not accurate. The role of clinical preparation and practical management is important, and the most important thing is to establish a planned induction strategy. Multiple factors system, such as simplified risk factors should be used to evaluate patients to prepare for appropriate airway management techniques in case of DI.
