AI Article Synopsis
- The study examines whether superior laryngeal nerve block (SLNB) can reduce coughing and improve sedation in patients undergoing maxillofacial surgery with delayed extubation.
- 60 patients were divided into two groups: one received standard anesthesia (control group) and the other received ultrasound-guided SLNB postoperatively (study group).
- Results showed that the SLNB group experienced less coughing and agitation, needed less rescue sedation, and enjoyed longer sedation periods, indicating SLNB improves postoperative outcomes.
Article Abstract
Objective: Superior laryngeal nerve block (SLNB) is a regional anesthesia technique for addressing airway response. However, SLNB on the efficacy of sedation in patients with delayed extubation is unknown, particularly for maxillofacial surgery (MS). The aim of the study was to assess whether ultrasound guided (UG) SLNB reduces the incidence of moderate to severe cough for delayed extubation in MS with free flap reconstruction.
Methods: 60 patients were randomly assigned to the GEA group (control group) and the SLNB group (UG-SLNB postoperatively, study group). During the initial two postoperative hours, the incidence of moderate and severe cough, agitation, and the number of patients requiring rescue propofol and flurbiprofen were recorded. Additionally, the time spent under the target level of sedation, postoperative hemodynamics, and the total does of propofol during the postoperative 24 h were recorded.
Results: The data showed the SLNB group had a significantly lower incidence of moderate to severe cough and agitation (p < 0.05), and a longer sedation time (p < 0.05). The number of patients required rescue propofol and flurbiprofen, as well as the hemodynamic changes, were significantly different between the two groups (p < 0.05).
Conclusion: The use of UG-SLNB is associated with reduced incidence of postoperative cough. Moreover, SLNB can enhance the efficacy of postoperative sedation with need of fewer agents postoperatively.

Effect of invasive acupuncture on awakening quality after general anesthesia: systematic review and meta-analysis.

Department of Anesthesiology, Affiliated Hospital of Shandong University of Traditional Chinese Medicine, Jinan, China.
Background: The process of waking up from general anesthesia is still not well understood, and recovery issues such as delayed awakening, agitation, postoperative cognitive dysfunction, continue to be a challenge for anesthesiologists. Currently, the treatment of these complications is mainly achieved through the antagonistic action of specific drugs, but sometimes the antagonistic drugs are not as effective as they should be and can add to the financial burden of the patient. Acupuncture, a common treatment in Traditional Chinese Medicine, is widely used around surgery.

Background: Endotracheal intubation and mechanical ventilation comprise common life support interventions for patients in intensive care units (ICUs). Premature or delayed extubation increases the risk of morbidity and mortality. Despite following weaning protocols, 10-20 % of patients fail extubation within 48 h.

Background: Critically ill ED patients on life support may undergo transition to comfort care as decided by the surrogate decision maker. When several hours are needed for loved ones to arrive and say farewell before initiating comfort care ("delayed comfort care"), these patients require prolonged ED stays or costly intensive care unit (ICU) admissions.
Methods: A novel ED observation unit (EDOU)-based delayed comfort care pathway for ED patients on invasive mechanical ventilation and/or vasopressors was created in 2013 at Stanford Hospital.
Early vs. Delayed Switching from Controlled to Assisted Ventilation: A Target Trial Emulation.

Radbound Univeristy Medical Center, Nijmegen, Netherlands;
Rationale: In critically ill patients receiving invasive mechanical ventilation, switching from controlled to assisted ventilation is a crucial milestone towards ventilator liberation. The optimal timing for switching to assisted ventilation has not been studied.
Objectives: Our objective was to determine whether a strategy of early as compared to delayed switching affects the duration of invasive mechanical ventilation, ICU length of stay, and mortality.

Background: Delayed extubation (DE) after cardiac surgery is associated with high morbidity, mortality, increased length of stay in the intensive care unit, and hospital costs. Various studies have identified factors that influence the occurrence of DE in patients after cardiac surgery, but no review has systematically synthesized the results.
Purpose: This review aimed to identify the influencing factors and the leading causes of DE in patients after cardiac surgery.
