Adverse Events in Anesthesia: An Integrative Review

Nanotherapeutics for Alleviating Anesthesia-Associated Complications

Current management of anesthesia-associated complications falls short in terms of both efficacy and safety. Nanomaterials with versatile properties and unique nano-bio interactions hold substantial promise as therapeutics for addressing these complications. This review conducts a thorough examination of the existing nanotherapeutics and highlights the strategies for developing prospective nanomedicines to mitigate anesthetics-related toxicity. Initially, general, regional, and local anesthesia along with the commonly used anesthetics and related prevalent side effects are introduced. Furthermore, employing nanotechnology to prevent and alleviate the complications of anesthetics is systematically demonstrated from three aspects, that is, developing 1) safe nano-formulization for anesthetics; 2) nano-antidotes to sequester overdosed anesthetics and alter their pharmacokinetics; 3) nanomedicines with pharmacodynamic activities to treat anesthetics toxicity. Finally, the prospects and challenges facing the clinical translation of nanotherapeutics for anesthesia-related complications are discussed. This work provides a comprehensive roadmap for developing effective nanotherapeutics to prevent and mitigate anesthesia-associated toxicity, which can potentially revolutionize the management of anesthesia complications.

Risk of Complications in Combined Plastic Surgery Procedures Using the Tracking Operations and Outcomes for Plastic Surgeons Database

BACKGROUND

Combining multiple surgical procedures into a single operative session is widespread in the field of plastic surgery; however, the implications of this practice are not fully understood.

OBJECTIVES

This study compared 30-day complication rates associated with combined plastic surgery procedures with the rates for index procedures.

METHODS

This retrospective cohort analysis utilized the Tracking Operations and Outcomes for Plastic Surgeons database from 2016 to 2020 to identify the 3 most frequent combinations of augmentation mammaplasty, reduction mammaplasty, trunk liposuction, mastopexy, and abdominoplasty.

RESULTS

The 30-day overall complication rate was 5.0% (1400 of 26,771 patients), with a higher complication rate for combined procedures compared with index (7.6% vs 4.2%, adjusted odd ratio [aOR], 1.91 [95% CI, 1.61-2.27], P < .001). There were no significant differences in complication rates for abdominoplasty or mastopexy combinations compared with index. Complication rates for reduction mammaplasty combinations compared with index were not statistically different after controlling for demographics (aOR, 1.02 [95% CI, 0.61-1.64], P = .93). Higher rates of minor and major complications were observed for combinations of trunk liposuction (aOR, 4.84 [95% CI, 3.31-7.21), P < .001) and augmentation mammaplasty (aOR, 1.60 [95% CI 1.13-2.22], P = .007) compared with index.

CONCLUSIONS

Combinations with trunk liposuction or augmentation mammaplasty present with increased risk of complications compared with index, controlling for demographics. Abdominoplasty and mastopexy may be combined with other plastic surgery procedures without increased risk to patients. The complication risk of reduction mammaplasty combinations is mediated by other variables, suggesting the need for shared surgical decision-making when recommending these combinations to patients.

Effect of implementing an anesthesia nurse checklist in a safety and teamwork climate: quasi-experimental study

OBJECTIVE

To evaluate the effect of implementing a Patient safety checklist: nursing in anesthetic procedure on the perception of safety climate and team climate of nurses and anesthesiologists from an operating room.

METHOD

Quasi-experimental study held in the operating room of a hospital in Brazil with a sample of nurses and anesthesiologists. The outcome was evaluated through the instruments "Safety Attitudes Questionnaire/Operating Room Version" and "Team Climate Inventory", applied before and after the implementation of a Patient safety checklist: nursing in anesthetic procedure by nurses. The mixed effects linear regression model was used to analyse the effect of the implementation.

RESULTS

Altogether, 19 (30.2%) nurses and 44 (69.8%) anesthesiologists participated in the study, implementing the Patient safety checklist: nursing in anesthetic procedure in 282 anesthesias. The Safety Attitudes Questionnaire/Operating Room Version score changed from 62.5 to 69.2, with modification among anesthesiologists in the domain "Perception of management" (p = 0.02). Between both professionals, the Team Climate Inventory score increased after the intervention (p = 0.01).

CONCLUSION

The implementation of the Patient safety checklist: nursing in anesthetic procedure changed the perception score of safety and teamwork climate, improving communication and collaborative work.

Adverse events in anesthesia: Analysis of claims against anesthetists affiliated to an insurance fund in Colombia. Cross-sectional study

Introduction: Prevention, identification, analysis and reduction of adverse events (AEs) are all activities designed to increase safety of care in the clinical setting. Closed claims reviews are a strategy that allows to identify patient safety issues. This study analyzes adverse events resulting in malpractice lawsuits against anesthesiologist affiliated to an insurance fund in Colombia between 2013-2019. Objective: To analyze adverse events in closed medicolegal lawsuits against anesthesiologist affiliated to an insurance fund between 2013-2019. Methods: Cross-sectional observational study. Convenience sampling was used, including all closed claims in which anesthesiologist affiliated to an insurance fund in Colombia were sued during the observation period. Variables associated with the occurrence of AEs were analyzed. Results: Overall, 71 claims were analyzed, of which 33.5% were due to anesthesia-related AEs. Adverse events were found more frequently among ASA I-II  patients (78.9%), and in surgical procedures (95.8%). The highest number of adverse events occurred in plastic surgery (29.6%); the event with the highest proportion was patient death (43.7%). Flaws in clinical records and failure to comply with the standards were found in a substantial number of cases. Conclusions: When compared with a previously published study in the same population, an increase in ethical, disciplinary and administrative claims was found, driven by events not directly related to anesthesia. Most of the anesthesia-related events occurred in the operating theater during surgical procedures in patients and procedures categorized as low risk, and most of them were preventable.

Role of perioperative nursing in anesthesia: a national overview

Abstract Objectives: To assess the actions performed by the operating room nurse during anesthesia and their behavior for patient safety regarding the reporting on adverse events, and to analyze their knowledge about anesthetic practices. Method: This is a cross-sectional study carried out using an electronic questionnaire consisting of socio-demographic, professional practice, knowledge in anesthesia, patient safety, and professional practice questions, conducted from January to March 2019 with operating room nurses. Results: One hundred nurses participated, 89 (89%) being women, with a mean age of 41.09 years (SD = 9.36), time of undergraduate completion of 14.33 years (SD = 8.34). The average attendance was 4.69 operating rooms (SD = 2.07) per nurse, with an emphasis on action before induction (49; 49%). Professionals reported performance of simultaneous activities (72; 72%) and insufficient number of employees (57; 57%) as difficulties of their daily practice. Among the participants, 77 (77%) correctly cited the periods of general anesthesia and 80.4% always reported the occurrence of an adverse event. Conclusion: Nurses identified their role in anesthesia, with limitations for assistance from multiple activities and lack of professionals.

Risk reduction in anesthesia and sedation-An analysis of process improvement towards zero adverse events

Introduction:

Anesthesia is a complex domain that is highly technical and skill based. Primary Care Physicians often have to do the initial evaluation of surgical patients they encounter during their daily practice before referring them to the surgical team. Thus, the Primary Care Physician's preliminary knowledge in anesthesia processes, risks involved and interventions that can be done to minimize these risks can improve patient-centered care and ultimately patient safety.

Materials and Methods:

The study was conceptualized and conducted in the Department of Anesthesiology from January 2018 to December 2018 in a 600 bed Multispecialty teaching hospital in Bihar, India. The study aimed towards Anesthesia Care related Risk Identification and Reduction and encompassed process improvements.

Results:

Risk Severity Analysis of the Critical Steps of Anesthesia Care was done. The average Hazard Score reduced from 21.59 during January 2018 to March 2018 to 8.23 during April 2018 to June 2018 subsequently to 3.53 during July 2018 to September 2018 and finally to 2.12 during October 2018 to December 2018. Thus, there was an overall reduction of 90.18% in the Hazard Score from April'18 to June'18 quarter to October 2018 to December 2018 quarter.

Conclusion:

Adverse Anesthesia/Sedation Events reported during the period from January 2019 to December 2019 was “Zero”. A systematic approach towards Risk Reduction not only lead to reduction in Hazard Score and Process Improvement but also made the Anesthesia Care Safe which is evident in the consistency of reporting “Zero” Adverse Anesthesia/Sedation Events for the last one year.
