Patient-Centered Outcomes after General and Spinal Anesthesia

Outcomes with spinal versus general anesthesia for patients with and without preoperative cognitive impairment: Secondary analysis of a randomized clinical trial

INTRODUCTION

The effect of spinal versus general anesthesia on the risk of postoperative delirium or other outcomes for patients with or without cognitive impairment (including dementia) is unknown.

METHODS

Post hoc secondary analysis of a multicenter pragmatic trial comparing spinal versus general anesthesia for adults aged 50 years or older undergoing hip fracture surgery.

RESULTS

Among patients randomized to spinal versus general anesthesia, new or worsened delirium occurred in 100/295 (33.9%) versus 107/283 (37.8%; odds ratio [OR] 0.85; 95% confidence interval [CI] 0.60 to 1.19) among persons with cognitive impairment and 70/432 (16.2%) versus 71/445 (16.0%) among persons without cognitive impairment (OR 1.02; 95% CI 0.71 to 1.47, p = 0.46 for interaction). Delirium severity, in-hospital complications, and 60-day functional recovery did not differ by anesthesia type in patients with or without cognitive impairment.

DISCUSSION

Anesthesia type is not associated with differences in delirium and functional outcomes among persons with or without cognitive impairment.

Impact of postoperative fatigue following minimally-invasive lumbar spine surgery

BACKGROUND

Postoperative fatigue is a distressing symptom and can have a major impact on the patient's quality of life after surgery. We investigate the extent of postoperative fatigue following minimally invasive spine surgery under general anesthesia (GA), and its impact on patients' quality of life (QOL) and activities of daily living (ADLs).

METHODS

We surveyed patients that underwent minimally-invasive lumbar spine surgery under GA within the previous year. A five-point Likert scale ("very much", "quite a bit", "somewhat", "a little bit", "not at all") was used to assess the extent of fatigue during the first postoperative month, its impact on QOL, and ADLs.

RESULTS

The survey was completed by 100 patients, 61% were male, mean age 64.6 ± 12.5 years, 31% underwent MIS-TLIF, 69% lumbar laminectomy. During the first postoperative month 45% of patients referred significant fatigue ("very much" or "quite a bit"); for 31% of patients fatigue significantly impacted their QOL; significantly limited their ADLs in 43% of patients. MIS-TLIF was associated with higher rate of postoperative fatigue compared to laminectomy (61.3% versus 37.7%, p = 0.02). Patients 65 years old or older had higher rates of fatigue compared to younger patients (55.6% versus 32.6%, p = 0.02). We did not observe a significant difference in postoperative fatigue between male and female patients.

CONCLUSIONS

Our study revealed a substantial incidence of postoperative fatigue in patients that underwent minimally-invasive lumbar spine surgery under GA, with a significant impact on QOL and ADLs. There is a need to research new strategies to reduce fatigue after spine surgery.

There is (probably) no (meaningful) difference in (most) outcomes between 'spinal' and 'general' anaesthesia for hip fracture surgery: time to move forward

A meta-analysis influenced by two recent large randomised controlled trials (REGAIN and RAGA) concluded that little, if any, difference in commonly measured outcomes exists between patients administered spinal or general anaesthesia for their hip fracture surgery. We explore whether there is genuinely no difference, or what the methodological problems in research might be that prevent any real difference from being observed. We also discuss the need for greater nuance in future research to determine how anaesthetists might deliver perioperative care towards improving postoperative recovery trajectories in patients following hip fracture.
