RESUMEN
BACKGROUND: Anesthetic techniques can affect perioperative neuroendocrine function. The objective of this study was to compare 3-month post-operative neuroendocrine functional outcomes between sevoflurane and propofol anesthesia in patients undergoing endoscopic transsphenoidal surgery (ETS) for removal of non-functional pituitary adenomas (NFPAs) retrospectively. METHODS: Among 356 patients who underwent ETS for removal of NFPAs under sevoflurane-remifentanil anesthesia (sevoflurane group, n = 103) or propofol-remifentanil anesthesia (propofol group, n = 253), 92 patients in each group were selected and their 3-month post-operative neuroendocrine functional outcomes (primary outcome measure) were compared after propensity score matching. RESULTS: Overall changes in post-operative 3-month neuroendocrine function compared to pre-operative baseline did not differ between the sevoflurane and propofol groups (worsened: 32.6% vs 29.3%, persistently decreased: 9.8% vs 12.0%, improved: 12.0% vs 20.7%, normalized: 9.8% vs 12.0%, persistently normal: 18.5% vs 19.6%; P = .400). The incidence of pituitary hormone deficiency at 3 months post-operatively did not differ between the sevoflurane and propofol groups (adrenocorticotropic hormone deficiency: 18.5% vs 17.4%, P = 1.000; thyroid-stimulating hormone deficiency: 10.9% vs 3.3%, P = .081; gonadotropin deficiency: 54.3% vs 48.9%, P = .555; growth hormone deficiency: 45.7% vs 48.9%, P = .768; panhypopituitarism: 1.1% vs 1.1%, P = 1.000). CONCLUSION: In patients undergoing ETS for removal of NFPAs, the effects of both sevoflurane-remifentanil and propofol-remifentanil anesthetic techniques on post-operative 3-month neuroendocrine functional outcomes were similar, suggesting that propofol and sevoflurane can be freely used in such patients in terms of post-operative intermediate-term neuroendocrine functional outcome.

BACKGROUND: Postoperative sore throat (POST) is a common, undesirable result of endotracheal intubation during general anaesthesia. This study aimed to evaluate the effectiveness of benzydamine hydrochloride (BH) spray in reducing the incidence of POST in paediatric patients. METHODS: This randomized, double-blind, prospective study included 142 children 6-12 years of age, who were randomly assigned to receive either BH spray or control. After induction of anaesthesia, direct laryngoscope was placed and BH spray was applied to the upper trachea and vocal cord in the BH group and intubation was performed using a cuffed tube lubricated with normal saline. Intubation in the control group was performed using a cuffed tube lubricated with normal saline without any intervention. The balloon was inflated to a pressure of 20 cmH2O. Patients were extubated after fully awakened and transferred to the post-anaesthetic care unit (PACU), where they were examined for the presence of POST and any adverse events 30 min after arrival to the PACU. Postoperative pain was evaluated using a smartphone application. RESULTS: Seventy-one patients were allocated to each group. The incidence of POST in the BH group did not differ from that in the control group (control: BH = 35 (49.3%): 42 (59.2%); P = 0.238); postoperative pain was also similar between the groups. Other complications, such as breath holding, secretions, coughing, laryngospasm and desaturation events, did not differ between the groups. CONCLUSIONS: Application of prophylactic BH spray to the vocal cords and upper trachea was not proven to reduce POST in paediatric patients.

BACKGROUND: Patients undergoing heart transplantation (HT) frequently receive perioperative red blood cell (RBC) transfusions, but the impact of perioperative transfusion on clinical outcomes after HT remains unclear. METHODS: All adult HTs performed in Korea between 2007 and 2016 were analyzed using data from the National Health Insurance Service. Patients were classified into four groups based on the number of RBC units transfused during hospital admission for HT: 0, 1 to 2, 3 to 5, and greater than or equal to 6 units. In-hospital and long-term mortality rates were compared among the groups. RESULTS: In total, 833 adults HTs were included in the study. The overall in-hospital mortality rate was 8.4% (70 of 833), with no mortality occurring in patients who received no transfusion. The in-hospital mortality rate was higher in patients requiring greater than or equal to 6 units (25.1%) than in patients who received 1 to 2 units (0.3%) and 3 to 5 units (2.7%; P < .001). Patients who received greater than or equal to 6 units of RBCs had a significantly higher risk of all-cause mortality after HT compared to patients who received no transfusion (hazard ratio [95% confidence interval], 5.99 [1.46-24.56]; P = .012). Long-term survival rate was also lower in patients who received transfusions of greater than or equal to 6 units of RBCs than in patients who received no transfusion (P < .001). CONCLUSIONS: Perioperative transfusion of greater than or equal to 6 units of RBCs may be associated with an increased risk of in-hospital and long-term mortality after HT.

Background: Single-injection adductor canal block (SACB) is one of the multimodal pain managements in total knee arthroplasty. The effect of an intrathecal local anesthetic is prolonged with an intraoperative dexmedetomidine infusion. Currently, SACB's effect along with the prolonged spinal anesthesia effect by dexmedetomidine has not been studied elsewhere. Methods: Seventy-eight patients were randomized to either the SACB group (n = 39) or the control group (n = 39). Spinal anesthesia and continuous infusion of dexmedetomidine were performed intraoperatively. The SACB was performed using 15 mL of either 0.5% ropivacaine or normal saline in postanesthesia care unit postoperatively. Primary endpoint examined the average numerical rating scale (NRS) pain scores at 2, 6, 12, and 24 hours after SACB while resting or moving. The secondary outcomes were the morphine equivalent, postoperative nausea and vomiting score, quadriceps strength, and overall satisfaction score. Results: The SACB group showed a lower average NRS pain score until 24 hours than the control group (2.4 vs 3.3 resting, 3.4 vs 4.1 moving). Resting and moving NRS scores at 6 and 12 hours were significantly lower in the SACB group, whereas no difference was found at 2, 24, and 48 hours, regardless of movement. The satisfaction score was higher in the SACB group than in the control group (9 [7.3-10.0] vs 7 [5.3-8.8]), and morphine equivalent at 2 hours was lower in the SACB group (2 [1-3]) than in the control group (2.9 [1.6-4]). Conclusions: SACB provided an additional analgesic effect in patients undergoing total knee arthroplasty under spinal anesthesia with continuous dexmedetomidine intravenous infusion.
RESUMEN
BACKGROUND: Anesthetic technique affects the neuroendocrine stress response to surgery. In this retrospective study, we compared the neuroendocrine stress response in patients undergoing endoscopic transsphenoidal pituitary adenoma surgery (ETSPAS) with total intravenous anesthesia (TIVA) with propofol-remifentanil or balanced anesthesia (BAL) with sevoflurane-remifentanil. MATERIALS AND METHODS: Eighty-nine patients undergoing ETSPAS were anesthetized with either propofol-remifentanil (TIVA group, n=62) or sevoflurane-remifentanil (BAL group, n=27). Data were retrospectively collected regarding preoperative and immediate postoperative serum levels of adrenocorticotropic hormone (ACTH) and cortisol (primary outcome measures), as well as other pituitary hormones and their target organ hormones (secondary outcome measures). RESULTS: There were no significant differences in preoperative pituitary hormone levels between the 2 groups. The immediate postoperative ACTH (89.5 [62.1 to 162.6] vs. 256.0 [92.0 to 570.7] pg/mL; P<0.001) level was lower in the TIVA group than in the BAL group, whereas immediate postoperative cortisol levels were similar between the 2 groups. The immediate postoperative thyroid-stimulating hormone (1.85 [1.21 to 2.98] vs. 1.21 [0.44 to 1.71] µIU/mL; P=0.003), triiodothyronine (91.0 [82.0 to 103.0] vs. 69.1 [64.6 to 76.2] ng/dL; P<0.001), luteinizing hormone (2.2 [1.2 to 4.0] vs. 1.0 [0.5 to 2.3] mIU/mL; P=0.005), and prolactin (22.6±15.8 vs. 12.8±10.2 ng/mL; P=0.005) levels were higher in the TIVA group compared with the BAL group. In both groups, none of the patients who had sufficient preoperative ACTH without hydrocortisone supplementation (n=15) showed hypocortisolism in the immediate postoperative measurement. CONCLUSIONS: Compared with BAL, TIVA resulted in reduced release of ACTH and increased release of thyroid-stimulating hormone, triiodothyronine, luteinizing hormone, and prolactin in patients undergoing ETSPAS.

BACKGROUND: TOFscan is a three-dimensional acceleromyography neuromuscular monitoring device that does not require initial calibration before muscle relaxant injection. This study aimed to compare TOFscan with TOF-Watch SX, the currently widely accepted uni-dimensional acceleromyography, for use among the pediatric population. We aimed to assess the agreement between TOFscan with TOF-Watch SX in the pediatric population's neuromuscular recovery. METHODS: A total of 35 children aged 6-12 years were enrolled. Prior to any muscle relaxant injection, TOFscan and TOF-Watch SX were applied at each opposite arm and monitoring began concurrently throughout neuromuscular recovery. Calibration was performed for TOF-Watch SX, and train-of-four values were recorded every 15 s. Agreement between the two devices was evaluated with Modified Bland-Altman analysis. RESULTS: The bias between TOF-Watch SX and TOFscan were all within the 95% limits of agreement. The bias and standard deviation were smaller and the limit of agreement was narrower in the normalized group than in the non-normalized group [normalized bias -0.002 (95% CI, -0.013 to 0.010), standard deviation (SD) 0.111 vs non-normalized bias 0.010 (95% CI, -0.003 to 0.0236), SD 0.127]. CONCLUSIONS: TOFscan reliably demonstrated lack of bias and good concordance with TOF-Watch SX throughout the neuromuscular recovery, especially when normalized. Despite technical limitations, the two devices were unbiased along the path of spontaneous and pharmacological reversal in pediatric patients. TRIAL REGISTRATION: ClinicalTrials.gov NCT03775603.
