The incidence of hypotension in parturients with coronavirus disease (COVID-19) undergoing regional anesthesia remains controversial. This study aimed to investigate the incidence of hypotension during spinal anesthesia in parturients infected with COVID-19, as well as to identify associated risk factors. Methods: This retrospective study compared COVID-19-positive parturients who underwent cesarean section under spinal anesthesia (COVID-19 group) with a control group between January 2017 and June 2022. We reviewed the medical records and collected the following information: basic patient characteristics, spinal anesthesia, and newborn-related data. Results: Compared with the control group, the COVID-19 group did not show any significant differences in terms of hypotension occurrence and vasopressor usage. A positive correlation was noted in the COVID-19 group between heart rate and duration of hospital stay (P < 0.001, Spearman’s rho = 0.422). In subgroup analysis of the COVID-19 group, group with a baseline heart rate ≥ 100 (group H) had lower Apgar scores at 1 min, longer hospital stays, and more severe COVID-19 symptoms than the with a baseline heart rate < 100 (group L). Moreover, in group H, there was a positive correlation between the heart rate and the lowest systolic blood pressure after spinal anesthesia (P = 0.012, Spearman’s rho = 0.528). Conclusions: Parturients with COVID-19 do not appear to have a higher risk of hypotension during cesarean section under spinal anesthesia than those without COVID-19. Given the close association between preoperative heart rate and extent of hypotension in parturients with COVID-19 undergoing spinal anesthesia, vigilant monitoring of vital signs by anesthesiologists is crucial during the perioperative period.

OBJECTIVES: Vacuum-assisted breast biopsy (VABB) is a widely used technique for the diagnosis of breast lesions. It is carried out with local anesthesia, but procedural pain and stress are still problematic. Dexmedetomidine is a α-2 receptor agonist that can sedate without significant respiratory depression. The study aimed to report the effectiveness of sedation with monitored anesthesia care (MAC) using dexmedetomidine in VABB. METHODS: This was a retrospective chart review of patients who received VABB under MAC with dexmedetomidine. Forty-seven patients during the period of February 2015 to July 2016 were included. We collected data on patient characteristics, infusion drug and dose, induction to incision time, anesthetic, operation, and recovery time and other complications and vital signs. RESULTS: The mean operating time was 50.1 ± 24.9 minutes, and the anesthetic time was 71.2 ± 28.3 minutes. The mean time from induction to incision was 17.0 ± 5.2 minutes, and the recovery time was 20.1 ± 10.3 minutes. None of the patients needed an advanced airway management. Further, none of them showed hemodynamic instability. CONCLUSIONS: VABB was successfully performed with MAC using dexmedetomidine, and there was no respiratory depression or hemodynamic instability.

Neonates undergoing surgery are at higher risk than older children for anesthesia-related adverse events. During the perioperative period, the maintenance of optimal hemodynamics in these patients is challenging and requires a thorough understanding of neonatal physiology and pharmacology. Data from animals and human cohort studies have shown relation of the currently used anesthetics may associate with neurotoxic brain injury that lead to later neurodevelopmental impairment in the developing brain. In this review, the unique neonatal physiologic and pharmacologic features and anesthesia-related neurotoxicity will be discussed.

BACKGROUND: Endovascular stent graft placement is a useful treatment option in lesions of the thoracic aorta. The aim of this study was to assess the possibility of sedation with dexmedetomidine compared with general anesthesia in patients undergoing thoracic endovascular aortic repair (TEVAR) in a multi-center clinical trial. METHODS: Data from 38 patients with thoracic aorta lesions treated by TEVAR between April 2010 and November 2013 were retrospectively collected at two hospitals. General anesthesia or sedation with dexmedetomidine was determined according to the hospital. Demographics, anesthetic recordings, and complications were reviewed. RESULTS: Stent graft placement was technically successful in all patients. There were no events during the anesthetic period. A total of 38 patients underwent TEVAR; 29 patients received general anesthesia, and 9 received sedation. Dexmedetomidine sedation (loading dose: 0.5-1.0 microg/kg for 10 min, maintenance: 0.2-0.8 microg/kg/h) was successfully performed without anesthesia-related complications or mortality. During the procedure, mean arterial pressure, heart rate, and saturation of peripheral oxygen were not statistically different between general anesthesia and dexmedetomidine sedation. CONCLUSIONS: In our study, TEVAR under sedation with dexmedetomidine was shown to be a feasible procedure that was well tolerated without specific complications.

BACKGROUND: The creation of pneumoperitoneum and Trendelenburg positioning during laparoscopic surgery are associated with respiratory changes. We aimed to compare respiratory mechanics while using intravenous propofol and remifentanil vs. sevoflurane during laparoscopic colectomy. METHODS: Sixty patients undergoing laparoscopic colectomy were randomly allocated to one of the two groups: group PR (propofol-remifentanil group; n = 30), and group S (sevoflurane group; n = 30). Peak inspiratory pressure (PIP), dynamic lung compliance (Cdyn), and respiratory resistance (Rrs) values at five different time points: 5 minutes after induction of anesthesia (supine position, T1), 3 minutes after pneumoperitoneum (lithotomy position, T2), 3 minutes after pneumoperitoneum while in the lithotomy-Trendelenburg position (T3), 30 minutes after pneumoperitoneum (T4), and 3 minutes after deflation of pneumoperitoneum (T5). RESULTS: In both groups, there were significant increases in PIP and Rrs while Cdyn decreased at times T2, T3, and T4 compared to T1 (P < 0.001). The Rrs of group PR for T2, T3, and T4 were significantly higher than those measured in group S for the corresponding time points (P < 0.05). CONCLUSIONS: Respiratory mechanics can be adversely affected during laparoscopic colectomy. Respiratory resistance was significantly higher during propofol-remifentanil anesthesia than sevoflurane anesthesia.
