Influence of changing trends in anaesthetic practice on morbidity and mortality in elderly patients undergoing lower limb surgery

Chan D, Y. Liu C. Effects of regional anaesthesia on mortality in patients undergoing lower extremity amputation: A retrospective pooled analysis

Background and Aims:

Lower extremity amputation (LEA) is a commonly performed surgery and is associated with significant mortality and morbidity. This review compares the impact of anaesthetic technique on 30-day mortality and other perioperative outcomes in patients undergoing LEA.

Methods:

A systematic search of databases including PubMed, Embase, Scopus and Cochrane Central Register of Controlled Trials, from January 2010 to March 2021, was performed. Studies were eligible if they compared 30-day mortality following either general anaesthesia (GA) or regional anaesthesia (RA), in adult patients undergoing LEA.

Results:

Ten retrospective observational studies were identified. Four of these studies utilised a propensity-score matching technique. Based on these four studies, RA when compared to GA, is not associated with a reduction in the 30-day mortality (Odds ratio 0.83, 95% confidence interval (CI): 0.65, 1.05, I² 20%, P = 0.12). Also there is a very low level of evidence that RA may result in a decrease in the hospital length-of-stay and intensive care unit admissions of patients undergoing LEA.

Conclusion:

RA does not decrease the 30-day postoperative mortality in patients undergoing LEA when compared to GA.

Nurses' role in recognising and responding to clinical deterioration in surgical patients

AIM AND OBJECTIVES

To explore nurse' role in recognising and responding to deteriorating post-operative patients.

BACKGROUND

Clinical deterioration is a significant problem in acute care settings. Nurses play a vital role in post-operative patient monitoring; however, there is limited understanding of the nurses' role in recognising and responding to clinical deterioration in surgical patients.

METHODS

This qualitative exploratory study was conducted at a metropolitan teaching hospital in Melbourne, Australia. Data were collected through focus groups from 1 September to 31 October 2014. Four focus groups of 2-5 surgical nurses (n = 14) were conducted to explore the nurses' perception of their role in managing deterioration over the first 72 hr postoperatively. Qualitative data were recorded, transcribed and key themes identified.

RESULTS

Nurses demonstrated a high level of awareness of their role in recognising and responding to early signs of deterioration. The themes that arose from the focus group interviews were "struggling with blood pressure," and "we know our patient is sick." The nurses were confident about the clinical indicators of deterioration and the appropriate channels to use to escalate care. Using track and trigger observation charts enabled nurses to identify deteriorating patients prior to the patient fulfilling rapid response system escalation criteria.

CONCLUSIONS

These findings highlight the importance of a collective team approach to preventing, recognising and responding to clinical deterioration across the whole patient journey. Initiatives to ensure accurate written and verbal communication between medical and nursing staff warrants further assessment.

RELEVANCE TO CLINICAL PRACTICE

Nurses working in acute surgical wards are highly engaged in the process of recognising and responding to clinical deterioration in post-operative patients. Many nurses reported being able to anticipate deterioration occurring but are required by current organisational frameworks to escalate care to rapid response systems. How nurses anticipate and manage deterioration prior to the patient fulfilling rapid response system criteria warrants further investigation.

One year of anaesthesia in France: A comprehensive survey based on the national medical information (PMSI) database. Part 1: In-hospital patients

Anaesthesia has evolved in France since the last epidemiologic survey in 1996. The national database program for medical information systems (the PMSI) can be used to track specific knowledge concerning anaesthesia for a selected period of time. The goal of this study was to perform a contemporary epidemiological description of anaesthesia in France for the year 2010.

METHODS

The data concerning private or public hospital stays were collected from the national PMSI database. All surgical/medical institutions performing anaesthesia in France and French Overseas Departments and Territories were queried concerning the number of anaesthesias, patient age, sex ratios, institution characteristics, hospitalization types, the duration of hospital stays, and the surgical procedures performed.

RESULTS

In 2010, the number of anaesthesia procedures performed was 11,323,630 during 8,568,630 hospital stays. We found that 9,544,326 (84.3%) anaesthetic procedures were performed in adults (> 18 years of age; excluding childbirth), 845,568 (7.5%) were related to childbirth and 933,736 (8.2%) were acts in children (up to 18 years of age). The mean duration of hospital stay was 5.7±8.2 days. 56.5% of adults and 39.5% of children were managed as inpatient hospital stays. The male/female sex ratio and mean age were 42/58 and 54±19 years, respectively. In adults, anaesthesia was predominantly performed for abdominal surgery (24.5%), orthopaedics (16.7%), gynaecology (10.3%), ophthalmology (9.7%) and vascular surgeries (7.1%). For paediatric populations, the main surgical activities were Ear-Nose-Throat surgery (43.1%), orthopaedic surgery (15.1%) and urological surgeries (12.8%).

DISCUSSION

The number of anaesthesias performed in France has dramatically increased (42.7%) since the last major epidemiological survey. Anaesthesia in the 21th century has been adapted to associated demographic changes: an older population with more comorbidities and fewer in-hospital procedures.
