ABSTRACT
Background@#Residual neuromuscular blockade (RNMB) is a frequent event after general anesthesia, which can lead to serious complications, such as upper airway obstruction. Sugammadex is useful in reversing RNMB. However, its use in infants has not yet been approved by the Food and Drug Administration. Therefore, anesthesiologists can be hesitant use it, even in situations where no other choice is available.Case: A two-month-old baby presented to the hospital for umbilical polypectomy. At the end of the surgery, neostigmine was administered. Even after waiting for 30 min and injecting an additional dose of neostigmine, neuromuscular blockade was not adequately reversed. Eventually, sugammadex was administered, and spontaneous breathing returned. @*Conclusions@#If there were no particular causes of delayed return to spontaneous breathing in infants, RNMB should be considered and reversal with sugammadex would be useful.
ABSTRACT
Background@#Peripheral nerve injury is a complication that can occur after general anesthesia. It significantly impairs the patient’s quality of life and may lead to permanent disability. Nerves in several areas can be damaged during the perioperative period, but it is very rare that numbness of the lower lip is caused after general anesthesia. Case: A 73-year-old man with diabetes mellitus underwent urological surgery under general anesthesia. The day after surgery, he complained of numbness on the right lower lip caused by a mental nerve injury. Diabetic mononeuropathy or neurapraxia related to mechanical compression was considered a possible cause. The symptoms resolved spontaneously after six weeks. @*Conclusions@#Mental nerve injury is a rare perioperative complication in surgical patients under general anesthesia. In this case, patients should be reassured and advised to avoid injuries to the mouth and lips. However, specific treatment is not required.

ABSTRACT
Background@#Prolotherapy, which stimulates the healing of loosened ligaments and tendons, is a cost-effective and safe treatment modality for chronic musculoskeletal pain. Its benefits may be affected by injection protocols, comparative regimens, and evaluation scales. The aim of this study was to determine the effectiveness of dextrose prolotherapy as a long-term treatment for chronic musculoskeletal pain. @*Methods@#Medline, Embase, Cochrane Central, KoreaMed, and KMbase databases were searched for studies published up to March 2019. We included randomized controlled trials which compared the effect of dextrose prolotherapy with that of other therapies such as exercise, saline, platelet-rich plasma, and steroid injection. The primary outcome was pain score change during daily life. @*Results@#Ten studies involving 750 participants were included in the final analysis. Pain scores from 6 months to 1 year after dextrose prolotherapy were significantly reduced compared to saline injection (standardized mean difference [SMD] –0.44; 95% confidence interval [CI] –0.76 to –0.11, P = 0.008) and exercise (SMD –0.42; 95% CI –0.77 to –0.07, P = 0.02). Prolotherapy yielded results similar to platelet-rich plasma or steroid injection, that it showed no significant difference in pain score. @*Conclusions@# Dextrose prolotherapy is more effective in the treatment of chronic pain compared to saline injection or exercise. Its effect was comparable to that of platelet-rich plasma or steroid injection. Adequately powered, homogeneous, and longer-term trials are needed to better elucidate the efficacy of prolotherapy.
ABSTRACT
BACKGROUND: Hip fracture surgery on elderly patients is associated with a high incidence of morbidity and mortality. The aim of this study is to identify the risk factors related to the postoperative mortality and complications following hip fracture surgery on elderly patients. METHODS: In this retrospective study, the medical records of elderly patients (aged 65 years or older) who underwent hip fracture surgery from January 2011 to June 2014 were reviewed. A total of 464 patients were involved. Demographic data of the patients, American Society of Anesthesiologists physical status, preoperative comorbidities, type and duration of anesthesia and type of surgery were collected. Factors related to postoperative mortality and complications; as well as to intensive care unit admission were analyzed using logistic regression. RESULTS: The incidence of postoperative mortality, cardiovascular complications, respiratory complications and intensive care unit (ICU) admission were 1.7, 4.7, 19.6 and 7.1%, respectively. Postoperative mortality was associated with preoperative respiratory comorbidities, postoperative cardiovascular complications (P < 0.05). Postoperative cardiovascular complications were related to frequent intraoperative hypotension (P <0.05). Postoperative respiratory complications were related to age, preoperative renal failure, neurological comorbidities, and bedridden state (P < 0.05). ICU admission was associated with the time from injury to operation, preoperative neurological comorbidities and frequent intraoperative hypotension (P < 0.05). CONCLUSIONS: Adequate treatment of respiratory comorbidities and prevention of cardiovascular complications might be the critical factors in reducing postoperative mortality in elderly patients undergoing hip fracture surgery.

BACKGROUND: During sedation with dexmedetomidine, a dose adjustment may be needed based on the invasiveness of the procedure, the patient's general condition, and their age. We aim here to determine the effective dose (ED) of dexmedetomidine to induce an adequate depth of sedation in elderly patients undergoing spinal anesthesia. METHODS: In this study, 47 patients aged 65 years or older, American Society of Anesthesiologists physical status I or II, undergoing spinal anesthesia were included. Patients were randomly allocated into group I, II, III, IV or V according to the dexmedetomidine loading dose of 0.1, 0.3, 0.5, 0.7 and 1.0 microg/kg, respectively. After spinal anesthesia, the assigned loading dose of dexmedetomidine was infused intravenously for 10 minutes, after which infusion was maintained at a rate of 0.3 microg/kg/h for the next 10 minutes in all groups. We assessed the depth of sedation with the Ramsay sedation scale every five minutes and measured vital signs and the oxygen saturation. The ED50 and ED95 of dexmedetomidine to obtain adequate sedation (Ramsay sedation score > or = 3) upon the completion of the loading dose were calculated with logistic regression. RESULTS: The ED50 and ED95 of dexmedetomidine for adequate sedation were 0.29 microg/kg (95% confidence intervals [CI] 0.14-0.44) and 0.86 microg/kg (95% CI 0.52-1.20), respectively. Hypotension was frequent in groups IV, V compared to groups I, II, III (31.6 vs. 3.6%, P = 0.013). CONCLUSIONS: ED95 of dexmedetomidine loading dose for adequate sedation is 0.86 microg/kg. However, dose higher than 0.5 microg/kg can lead to hemodynamic instability.
