Abstract
INTRODUCTION Deep brain stimulation (DBS) is a well-established surgical therapy for patients with Parkinsons' Disease (PD). Traditionally, DBS surgery for PD is performed under local anesthesia, whereby the patient is awake to facilitate intraoperative neurophysiological confirmation of the intended target using microelectrode recordings. General anesthesia allows for improved patient comfort without sacrificing anatomic precision and clinical outcomes. METHODS We performed a systemic review and meta-analysis on patients undergoing DBS for PD. Published randomized controlled trials, prospective and retrospective studies, and case series which compared asleep and awake techniques for patients undergoing DBS for PD were included. A total of 19 studies and 1,900 patients were included in the analysis. RESULTS We analyzed the (i) clinical effectiveness - postoperative UPDRS III score, levodopa equivalent daily doses and DBS stimulation requirements. (ii) Surgical and anesthesia related complications, number of lead insertions and operative time (iii) patient's quality of life, mood and cognitive measures using PDQ-39, MDRS, and MMSE scores. There was no significant difference in results between the awake and asleep groups, other than for operative time, for which there was significant heterogeneity. CONCLUSION With the advent of newer technology, there is likely to have narrowing differences in outcomes between awake or asleep DBS. What would therefore be more important would be to consider the patient's comfort and clinical status as well as the operative team's familiarity with the procedure to ensure seamless transition and care.

Intraoperative suggestions to prevent postoperative delirium in patients undergoing transaortic valvular replacement: a randomized placebo-controlled trial. Aging Clin Exp Res 2023; 35:1865-1872. [PMID: 37392348 PMCID: PMC10460361 DOI: 10.1007/s40520-023-02476-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2022] [Accepted: 06/06/2023] [Indexed: 07/03/2023]
Abstract
BACKGROUND Postoperative delirium (POD) is a serious complication following anaesthesia and surgery and significantly influences postoperative outcome especially in the elderly population. Intraoperative music and positive suggestions influence postoperative outcomes by attenuating analgesic demand and increasing patient satisfaction. AIMS Here, we examined the effect of intraoperative music and positive suggestions on the development of POD in aged patients undergoing transcatheter aortic valve replacement (TAVR) procedure under general anaesthesia. METHODS For this randomized placebo-controlled study, eligible patients without cognitive deficit, indicated by a MMSE < 10 points, were anesthetized using remifentanil and sevoflurane. Anaesthetic depth was guide with bispectral index. An audiotape with positive suggestions was applied from a MP3 player via headphones. POD, pain and PONV was assessed. CAM-ICU and Nu-DESC were done twice daily for the first 5 days. RESULTS Of 140 patients 118 patients could be analysed (57 male, 80.6 ± 5.1 years). POD was diagnosed in 16 patients (12.7%). POD was significantly more often observed in male (12, 21.1%) than in female (4, 6.6%, p = 0.02) and in patients with a low MMSE (23.6 ± 4.5 vs. 26.8 ± 2.8, p = 0.001). Anaesthetic depth did not influence the incidence of POD. Intraoperative music and suggestions did not affect the rate of POD, pain, analgesic requirement or PONV. DISCUSSION In patients undergoing TAVR male sex and low MMSE scoring are associated with an increase in POD. CONCLUSIONS Intraoperative music and positive suggestions do not influence the incidence of POD in this patient group.

J Am Geriatr Soc 2023; 71:646-660. [PMID: 36419366 DOI: 10.1111/jgs.18104] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2022] [Revised: 08/19/2022] [Accepted: 09/24/2022] [Indexed: 11/25/2022]
Abstract
AIMS To perform an updated systematic review and meta-analysis of postoperative delirium (POD) after transcatheter aortic valve replacement (TAVR). METHODS We conducted a systematic literature search of PubMed, Embase, and Cochrane Library databases from the time of the first human TAVR procedure in 2002 until December 24, 2021, which was supplemented by manual searches of bibliographies. Data were collected on incidence rates, risk factors, and/or associated mortality of POD after TAVR. Pooled analyses were conducted using random effects models to yield mean differences, odds ratios, hazard ratios, and risk ratios, with 95% confidence intervals. RESULTS A total of 70 articles (69 studies) comprising 413,389 patients were included. The study heterogeneity was substantial. The pooled mean incidence of POD after TAVR in all included studies was 9.8% (95% CI: 8.7%-11.0%), whereas that in studies using validated tools to assess for delirium at least once a day for at least 2 consecutive days after TAVR was 20.7% (95% CI: 17.8%-23.7%). According to the level of evidence and results of meta-analysis, independent preoperative risk factors with a high level of evidence included increased age, male sex, prior stroke or transient ischemic attack, atrial fibrillation/flutter, weight loss, electrolyte abnormality, and impaired Instrumental Activities of Daily Living; intraoperative risk factors included non-transfemoral access and general anesthesia; and acute kidney injury was a postoperative risk factor. POD after TAVR was associated with significantly increased mortality (pooled unadjusted RR: 2.20, 95% CI: 1.79-2.71; pooled adjusted RR: 1.62, 95% CI: 1.25-2.10), particularly long-term mortality (pooled unadjusted HR: 2.84, 95% CI: 1.91-4.23; pooled adjusted HR: 1.88, 95% CI: 1.30-2.73). CONCLUSIONS POD after TAVR is common and is associated with an increased risk of mortality. Accurate identification of risk factors for POD after TAVR and implementation of preventive measures are critical to improve prognosis.

Influence of Narcotrend-Assisted Anesthesia In-Depth Monitor on Cognitive Impairment of Elderly Patients under General Anesthesia. COMPUTATIONAL AND MATHEMATICAL METHODS IN MEDICINE 2022; 2022:2866188. [PMID: 36267318 PMCID: PMC9578890 DOI: 10.1155/2022/2866188] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/23/2022] [Accepted: 09/29/2022] [Indexed: 11/17/2022]
Abstract
Objective This research is designed to probe into the influence of Narcotrend- (NT-) assisted anesthesia in-depth monitor on cognitive impairment of elderly patients under general anesthesia (GA). Methods One hundred and forty-four elderly patients with GA in our hospital from October 2020 to April 2021 were randomized into two groups, namely, NT group (supervised anesthesia under NT monitoring) and group C (anesthesia according to doctors' experience). The heart rate (HR), mean arterial pressure (MAP), and central venous pressure (CVP) were recorded before surgery (T0), at the beginning of surgery (T1), at the end of surgery (T2), and 1 day after surgery (T3). Serum of patients was obtained at these four time points for measurements of C-reactive protein (CRP), interleukin-6 (IL-6), and cortisol (Cor) levels using the enzyme-linked immunosorbent assay (ELISA). The alterations in cognitive function pre- and post-anesthesia were assessed using the mini-mental state examination (MMSE), and adverse events (AEs) during anesthesia recovery, postoperative recovery, and dosage of anesthetics were recorded. Results At T1 and T2, MAP was higher and CVP was lower in NT group, versus group C. NT group presented higher CRP, IL-6, and Cor than group C at T1-T3. MMSE scores were higher in TN group than in group C at 12, 24, and 48 h after surgery. The incidence rates of postoperative cognitive dysfunction (POCD) and total AEs in group C were noticeably higher than those in NT group. Compared with group C, the time of anesthesia recovery, extubation, and postanesthesia care unit (PACU) residence in NT group reduced remarkably. Conclusions NT has little effect on the physical condition of elderly patients under GA, and can reduce the dosage of narcotic drugs and promote the recovery of patients from anesthesia, which has high clinical value.
