Predictor role of heart rate variability in subarachnoid hemorrhage: A systematic review.

Background- Subarachnoid hemorrhage (SAH) is one of the most devastating diseases with a high rate of morbidity and mortality. The heart rate variability (HRV) is a non-invasive method of monitoring various components of the autonomic nervous system activity that can be utilized to delineate autonomic dysfunctions associated with various physiological and pathological conditions. The reliability of HRV as a predictor of clinical outcome in aneurysmal subarachnoid hemorrhage (aSAH) is not yet well investigated in literature. Methods- A systematic review and in depth analysis of 10 articles on early HRV changes in SAH patients was performed. Results- This systematic review demonstrates a correlation between early changes in HRV indices (time and frequency domain) and the development of neuro-cardiogenic complications and poor neurologic outcome in patients with SAH. Conclusions- A correlation between absolute values or changes of the LF/HF ratio and neurologic and cardiovascular complications was found in multiple studies. Because of significant limitations of included studies, a large prospective study with proper handling of confounders is needed to generate high-quality recommendations regarding HRV as a predictor of post SAH complications and poor neurologic outcome.

Second victim support structures in anaesthesia: a cross-sectional survey in Belgian anaesthesiologists.

BACKGROUND: Anaesthesiologists are prone to patient safety situations after which second victim symptoms can occur. In international literature, a majority of these second victims indicated that they were emotionally affected in the aftermath of a patient safety incident (PSI) and received little institutional support after these events. OBJECTIVE: To study the current second victim support structures in anaesthesia departments in Belgium. METHODS: An observational cross-sectional survey. Belgian anaesthesiologists and anaesthesiologists in training were contacted through e-mail from May 27th until 15 July 2020. RESULTS: In total, 456 participants completed the online survey. 73.7% (n = 336) of the participants encountered a PSI during the last year of their medical practice. 80.9% (n = 368) of respondents answered that they do discuss incidents with their colleagues. 18.0% (n = 82) discussed all incidents. 19.3% (n = 88) admitted that these incidents are never discussed in their department. 15.4% of participants (n = 70) experienced or thought that the culture is negative during these PSI discussions. 17.3% (n = 79) scored the culture neutral. Anaesthesiologists who encountered a PSI in the last years scored the support of their anaesthesia department a mean score of 1.59 (ranging from -10 to +10). A significant correlation (P < 0.05) was found between the culture during the morbidity and mortality meetings, the support after the incidents and the perceived quality of the anaesthesia department. CONCLUSION: Of the participating anaesthesiologist in Belgium, 80.9% discussed some PSIs and 18.0% discussed all PSIs as a normal part of their staff functioning with an experienced positive or neutral culture during these meetings in 84.6%. Psychological safety within the anaesthesiology departments is globally good; however, it could and should be optimized. This optimization process warrants further investigations in the future.

Anesthetic considerations in children with Hutchinson-Gilford progeria syndrome: A narrative review.

BACKGROUND: Hutchinson-Gilford progeria syndrome is a rare disease in childhood that results in premature aging. The presence of multisystem derangements including skin, bone, and joint diseases and possibly a difficult airway makes the anesthetic management challenging. Because of the extremely low prevalence, experience is limited even for experienced pediatric anesthesiologists. OBJECTIVE: To review the available literature on anesthesia for patients with Hutchinson-Gilford progeria syndrome and to give recommendations for establishing the best practice for patients with Hutchinson-Gilford progeria syndrome. DESIGN: A narrative review of the rare existing literature. DATE SOURCES: CENTRAL (Cochrane), EMBASE, Google Scholar, MEDLINE and PubMed. ELIGIBILITY CRITERIA: Articles addressing anesthesia in patients with Hutchinson-Gilford progeria syndrome were included. RESULTS: An overview of the current literature was made on anesthesia care for patients with Hutchinson-Gilford progeria syndrome. After screening the literature, only ten articles were found to be of interest and include some case reports and a correspondence. The focus points on how to perform anesthesia care in patients with Hutchinson-Gilford progeria syndrome and the entire perioperative care are suggested. The available data are limited and results need to be interpreted with caution. CONCLUSION: The patients with Hutchinson-Gilford progeria syndrome are not just "frail" patients. Awareness concerning intubation difficulties is mandatory, and airway strategies must be addressed in advance. Although these patients present with the physiology of an elderly with accompanying comorbidities, emotionally they are only children and should be approached as such.

Sumatriptan for Postcraniotomy Headache after Minimally Invasive Craniotomy for Clipping of Aneurysms: A Prospective Randomized Controlled Trial.

Introduction Postcraniotomy headaches are often underestimated and undertreaded. This study aimed to identify if postoperative administration of sumatriptan after minimally invasive craniotomy for clipping an unruptured aneurysm could reduce postcraniotomy headache and improve the quality of postoperative recovery. Settings and Design Tertiary care center, single-center randomized double-blind placebo-controlled trial. Materials and Methods Patients who complained of postoperative headaches after minimally invasive craniotomy for clipping of unruptured aneurysms were randomized to receive subcutaneous sumatriptan (6 mg) or placebo. The primary outcome was the quality of recovery measured 24 hours after surgery. Secondary outcomes were total opioid use and headache score at 24 hours after surgery. Data were analyzed using a Student's t -test or the chi-square test. Results Forty patients were randomized to receive sumatriptan ( n = 19) or placebo ( n = 21). Both groups had similar demographics, comorbidities, and anesthesia management. The Quality of Recovery 40 score was higher for patients receiving sumatriptan compared to placebo, however, not statistically significant (173 [156-196] vs. 148 [139-181], p = 0.055). Postoperative opioid use between sumatriptan and placebo was lower, but not significant (5.4 vs. 5.6 mg morphine equivalent, p = 0.71). The severity of headache was also not statistically different between the two groups (5 [4-5] vs. 4 [2-5], p = 0.155). Conclusion In patients undergoing minimally invasive craniotomies for aneurysm clipping, sumatriptan given postoperatively has a nonsignificant trend for a higher quality of recovery. Similarly, there was a nonsignificant trend toward lower postcraniotomy headache scores and opioid scores for the patient given sumatriptan.

Axillary Brachial Plexus Block Compared with Other Regional Anesthesia Techniques in Distal Upper Limb Surgery: A Systematic Review and Meta-Analysis.

Background: Several regional anesthesia (RA) techniques have been described for distal upper limb surgery. However, the best approach in terms of RA block success rate and safety is not well recognized. Objective: To assess and compare the surgical anesthesia and efficacy of axillary brachial plexus block with other RA techniques for hand and wrist surgery. The attainment of adequate surgical anesthesia 30 min after block placement was considered a primary outcome measure. Additionally, successful block outcomes were required without the use of supplemental local anesthetic injection, systemic opioid analgesia, or the need to convert to general anesthesia. Methods: We performed a systematic search in the following databases: MEDLINE, EMBASE, Cochrane Database of Systematic Reviews, and CENTRAL. RCTs comparing axillary blocks with other brachial plexus block techniques, distal peripheral forearm nerve block, intravenous RA, and the wide-awake local anesthesia no tourniquet (WALANT) technique were included. Results: In total, 3070 records were reviewed, of which 28 met the inclusion criteria. The meta-analysis of adequate surgical anesthesia showed no significant difference between ultrasound-guided axillary block and supraclavicular block (RR: 0.94 [0.89, 1.00]; p = 0.06; I2 = 60.00%), but a statistically significant difference between ultrasound-guided axillary block and infraclavicular block (RR: 0.92 [0.88, 0.97]; p < 0.01; I2 = 53.00%). Ultrasound-guided infraclavicular blocks were performed faster than ultrasound-guided axillary blocks (SMD: 0.74 [0.30, 1.17]; p < 0.001; I2 = 85.00%). No differences in performance time between ultrasound-guided axillary and supraclavicular blocks were demonstrated. Additionally, adequate surgical anesthesia onset time was not significantly different between ultrasound-guided block approaches: ultrasound-guided axillary blocks versus ultrasound-guided supraclavicular blocks (SMD: 0.52 [-0.14, 1.17]; p = 0.12; I2 = 86.00%); ultrasound-guided axillary blocks versus ultrasound-guided infraclavicular blocks (SMD: 0.21 [-0.49, 0.91]; p = 0.55; I2 = 92.00%). Conclusions: The RA choice should be individualized depending on the patient, procedure, and operator-specific parameters. Compared to ultrasound-guided supraclavicular and infraclavicular block, ultrasound-guided axillary block may be preferred for patients with significant concerns of block-related side effects/complications. High heterogeneity between studies shows the need for more robust RCTs.

Same-day discharge after craniotomy for tumor resection: a retrospective observational single-center study of 630 patients.

OBJECTIVE: Modern neurosurgical developments enable minimally invasive surgery with shorter operation times, faster recovery, and earlier hospital discharge. These in combination with Enhanced Recovery After Surgery (ERAS) protocols have the potential to safely shift craniotomy for tumor resection to the ambulatory setting in selected patients. The aim of this retrospective observational single-center study was to assess the success rate of planned same-day discharge from hospital in patients undergoing craniotomy for supratentorial brain tumor resection under general anesthesia or awake craniotomy as well as to explore potential associations with anesthesia techniques, complications, and readmission rates. METHODS: A retrospective analysis of all patients scheduled for same-day discharge after supratentorial craniotomy for tumor resection over 25 years (1996-2021) was performed. Patients were identified for same-day discharge based on specific inclusion and exclusion criteria. Data collected included patient demographics, comorbidities, anesthetic data, perioperative complications, and patient dispositions. Data are presented descriptively. RESULTS: A total of 630 patients (mean age 50.9 years; 311 females, 319 males) scheduled for same-day discharge were analyzed. Patients underwent either awake craniotomy (AC; n = 491) or craniotomy under general anesthesia (GA; n = 139). Successful preplanned same-day discharge occurred in 571 (90.6%). Failed same-day discharge happened in 59 patients (GA, n = 14; AC, n = 45). Reasons for failed discharge included the following: new neurological deficit (n = 28); presence of seizure (n = 8); postoperative nausea and vomiting (PONV; n = 12); excessive headache (n = 5); and/or social factors (n = 10). Nine patients (1.4%) (GA, n = 0; AC, n = 9) with same-day discharge required readmission to hospital within the first 24 hours after discharge. Reasons for readmission included headache (n = 2), seizure (n = 4), neurological deficit (n = 3), and/or PONV (n = 1); all patients were successfully discharged from hospital after 1 day with no need for reoperation. CONCLUSIONS: This retrospective, single-center analysis shows that same-day discharge after craniotomy can be safe in carefully selected patients after both GA and AC for tumor resection. Multidisciplinary involvement (surgeons, anesthesiologists, nurses, and other allied health professionals) optimizes success of same-day craniotomy programs. Future optimization of analgesia and prevention of PONV has the potential to increase the success rate.

Regional anaesthesia for ambulatory surgery.

Regional anaesthesia (RA) has an important and ever-expanding role in ambulatory surgery. Specific practices vary depending on the preferences and resources of the anaesthesia team and hospital setting. It is used for various purposes, including as primary anaesthetic technique for surgery but also as postoperative analgesic modality. The limited duration of action of currently available local anaesthetics limits their application in postoperative pain control and enhanced recovery. The search for the holy grail of regional anaesthetics continues. Current evidence suggests that a peripheral nerve block performed with long-acting local anaesthetics in combination with intravenous or perineural dexamethasone gives the longest and most optimal sensory block. In this review, we outline some possible blocks for ambulatory surgery and additives to perform RA. Moreover, we give an update on local anaesthesia drugs and adjuvants, paediatric RA in ambulatory care and discuss the impact of RA by COVID-19.

Efficacy of ultrasound-guided forearm nerve block versus forearm intravenous regional anaesthesia in patients undergoing carpal tunnel release: A randomized controlled trial.

BACKGROUND AND OBJECTIVES: Distal upper extremity surgery is commonly performed under regional anaesthesia, including intravenous regional anaesthesia (IVRA) and ultrasound-guided forearm nerve block. This study aimed to investigate if ultrasound-guided forearm nerve block is superior to forearm IVRA in producing a surgical block in patients undergoing carpal tunnel release. METHODS: In this observer-blinded, randomized controlled superiority trial, 100 patients undergoing carpal tunnel release were randomized to receive ultrasound-guided forearm nerve block (n = 50) or forearm IVRA (n = 50). The primary outcome was anaesthetic efficacy evaluated by classifying the blocks as complete vs incomplete. Complete anaesthesia was defined as total sensory block, incomplete anaesthesia as mild pain requiring more analgesics or need of general anaesthesia. Pain intensity on a numeric rating scale (0-10) was recorded. Surgeon satisfaction with hemostasis, surgical time, and OR stay time were recorded. Patient satisfaction with the quality of the block was assessed at POD 1. RESULTS: In total, 43 (86%) of the forearm nerve blocks were evaluated as complete, compared to 33 (66%) of the forearm IVRA (p = 0.019). After the forearm nerve block, pain intensity was lower at discharge (-1.76 points lower, 95% CI (-2.92, -0.59), p = 0.0006) compared to patients treated with forearm IVRA. No differences in pain experienced at the start of the surgery, during surgery, and at POD1, nor in surgical time or total OR stay were observed between groups. Surgeon (p = 0.0016) and patient satisfaction (p = 0.0023) were slightly higher after forearm nerve block. CONCLUSION: An ultrasound-guided forearm nerve block is superior compared to forearm IVRA in providing a surgical block in patients undergoing carpal tunnel release. TRIAL REGISTRATION: This trial was registered as NCT03411551.

The analgesic efficacy of forearm versus upper arm intravenous regional anesthesia (Bier's block): A randomized controlled non-inferiority trial.

STUDY OBJECTIVE: This study aimed to assess if a forearm (FA) intravenous regional anesthesia (IVRA) with a lower, less toxic, local anesthetic dosage is non-inferior to an upper arm (UA) IVRA in providing a surgical block in patients undergoing hand and wrist surgery. DESIGN: Observer-blinded, randomized non-inferiority study. SETTING: Operating room. PATIENTS: 280 patients undergoing hand surgery were randomly assigned to UA IVRA (n = 140) or FA IVRA (n = 140). INTERVENTIONS: Forearm IVRA or upper arm IVRA in patients undergoing hand and wrist surgery. MEASUREMENTS: The primary outcome was block success rate of both techniques. Block success was defined as no need of additional analgesics. A second, alternative non-inferiority outcome was defined as no need of conversion to general anesthesia. A difference in success rate of <5% was considered non-inferior. Secondary endpoints were tourniquet pain measured with a Numerical Rating Scale (0-10), satisfaction of patients and surgeons, onset time, surgical time and total OR time. MAIN RESULTS: Non-inferiority of block success rate, defined as no need of additional analgesics or conversion to general anesthesia was inconclusive (5.24%, 95% CI:-4.34%,+14.82%). Non-inferiority of no need of conversion to general anesthesia was confirmed (+0.73%, 95% CI:-0.69%,+2.15%). No differences were observed in onset time (FA: 5 (5, 8) vs UA: 6 (5, 7) min, p = 0.74), surgical time (FA: 8 (5, 12) vs UA: 7 (5, 11) min, p = 0.71), nor total OR stay time (FA: 34 (27, 41) vs UA: 35 (32, 39) min, p = 0.09). Tourniquet pain after 10 min was significantly lower after FA IVRA compared to UA IVRA (FA: 2.00 (0.00, 4.00) vs UA: 3.00 (1.00,5.00) min, p = 0.003). CONCLUSION: We failed to demonstrate non-inferiority of forearm IVRA with a lower dosage of LA in providing a surgical block without rescue opioids and LA. Non-inferiority of no need of conversion to general anesthesia was confirmed.

Neurological outcome after minimally invasive coronary artery bypass surgery (NOMICS): An observational prospective cohort study.

BACKGROUND/OBJECTIVES: Endoscopic coronary artery bypass grafting (Endo-CABG) is a minimally invasive CABG procedure with retrograde arterial perfusion. The main objective of this study is to assess neurocognitive outcome after Endo-CABG. METHODS/DESIGN: In this prospective observational cohort study, patients were categorised into: Endo-CABG (n = 60), a comparative Percutaneous Coronary Intervention (PCI) group (n = 60) and a healthy volunteer group (n = 60). A clinical neurological examination was performed both pre- and postoperatively, delirium was assessed postoperatively. A battery of 6 neurocognitive tests, Quality of life (QoL) and the level of depressive feelings were measured at baseline and after 3 months. Patient Satisfaction after Endo-CABG was assessed at 3-month follow-up. Primary endpoints were incidence of postoperative cognitive dysfunction (POCD), stroke and delirium after Endo-CABG. Secondary endpoints were QOL, patient satisfaction and the incidence of depressive feelings after Endo-CABG. RESULTS: In total, 1 patient after Endo-CABG (1.72%) and 1 patient after PCI (1.67%) suffered from stroke during the 3-month follow-up. POCD in a patient is defined as a Reliable Change Index ≤-1.645 or Z-score ≤-1.645 in at least two tests, and was found in respectively 5 and 6 patients 3 months after Endo-CABG and PCI. Total incidence of POCD/stroke was not different (PCI: n= 7 [15.9%]; Endo-CABG: n= 6 [13.0%], p = 0.732). ICU delirium after Endo-CABG was found in 5 (8.6%) patients. QoL increased significantly three months after Endo-CABG and was comparable with QoL level after PCI and in the control group. Patient satisfaction after Endo-CABG and PCI was comparable. At follow-up, the level of depressive feelings was decreased in all groups. CONCLUSIONS: The incidence of poor neurocognitive outcome, including stroke, POCD and postoperative ICU delirium until three months after Endo-CABG is low and comparable with PCI. TRIAL REGISTRATION: Registered on ClinicalTrials.gov (NCT02979782).

Neurological outcome after minimal invasive coronary artery surgery (NOMICS): protocol for an observational prospective cohort study.

INTRODUCTION: Adverse neurocognitive outcomes are still an important cause of morbidity and mortality after cardiac surgery. The most common neurocognitive disorders after conventional cardiac surgery are postoperative cognitive dysfunction (POCD), stroke and delirium. Minimal invasive cardiac procedures have recently been introduced into practice. Endoscopic coronary artery bypass grafting (Endo-CABG) is a minimal invasive cardiac procedure based on the conventional CABG procedure. Neurocognitive outcome after minimal invasive cardiac surgery, including Endo-CABG, has never been studied. Therefore, the main objective of this study is to examine neurocognitive outcome after Endo-CABG. METHODS AND ANALYSIS: We will perform a prospective observational cohort study including 150 patients. Patients are categorised into three groups: (1) patients undergoing Endo-CABG, (2) patients undergoing a percutaneous coronary intervention and (3) a healthy volunteer group. All patients in the Endo-CABG group will be treated following a uniform, standardised protocol. To assess neurocognitive outcome after surgery, a battery of six neurocognitive tests will be administered at baseline and at 3-month follow-up. In the Endo-CABG group, a neurological examination will be performed at baseline and postoperatively and delirium will be scored at the intensive care unit. Quality of life (QOL), anxiety and depression will be assessed at baseline and at 3-month follow-up. Satisfaction with Endo-CABG will be assessed at 3-month follow-up. Primary endpoints are the incidence of POCD, stroke and delirium after Endo-CABG. Secondary endpoints are QOL after Endo-CABG, patient satisfaction with Endo-CABG and the incidence of anxiety and depression after Endo-CABG. ETHICS AND DISSEMINATION: The neurological outcome after minimal invasive coronary artery surgery study has received approval of the Jessa Hospital ethics board. It is estimated that the trial will be executed from December 2016 to January 2018, including enrolment and follow-up. Analysis of data, followed by publication of the results, is expected in 2018. TRIAL REGISTRATION NUMBER: NCT02979782.
