Cerebral autoregulation derived blood pressure targets in elective neurosurgery. J Clin Monit Comput 2024; 38:649-662. [PMID: 38238636 PMCID: PMC11164832 DOI: 10.1007/s10877-023-01115-0] [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: 08/27/2023] [Accepted: 11/23/2023] [Indexed: 06/11/2024]
Abstract
Poor postoperative outcomes may be associated with cerebral ischaemia or hyperaemia, caused by episodes of arterial blood pressure (ABP) being outside the range of cerebral autoregulation (CA). Monitoring CA using COx (correlation between slow changes in mean ABP and regional cerebral O2 saturation-rSO2) could allow to individualise the management of ABP to preserve CA. We aimed to explore a continuous automated assessment of ABPOPT (ABP where CA is best preserved) and ABP at the lower limit of autoregulation (LLA) in elective neurosurgery patients. Retrospective analysis of prospectively collected data of 85 patients [median age 60 (IQR 51-68)] undergoing elective neurosurgery. ABPBASELINE was the mean of 3 pre-operative non-invasive measurements. ABP and rSO2 waveforms were processed to estimate COx-derived ABPOPT and LLA trend-lines. We assessed: availability (number of patients where ABPOPT/LLA were available); time required to achieve first values; differences between ABPOPT/LLA and ABP. ABPOPT and LLA availability was 86 and 89%. Median (IQR) time to achieve the first value was 97 (80-155) and 93 (78-122) min for ABPOPT and LLA respectively. Median ABPOPT [75 (69-84)] was lower than ABPBASELINE [90 (84-95)] (p < 0.001, Mann-U test). Patients spent 72 (56-86) % of recorded time with ABP above or below ABPOPT ± 5 mmHg. ABPOPT and ABP time trends and variability were not related to each other within patients. 37.6% of patients had at least 1 hypotensive insult (ABP < LLA) during the monitoring time. It seems possible to assess individualised automated ABP targets during elective neurosurgery.

[PMID: 38306533 PMCID: PMC10843472 DOI: 10.1097/md.0000000000037072] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/17/2023] [Accepted: 11/14/2023] [Indexed: 02/04/2024] Open
Abstract
The purpose of the current study is to analyze whether surgical starting time affects the short-term outcomes of elective colorectal cancer (CRC) surgery. We retrospectively collected CRC patients who underwent elective surgery from Jan 2008 to Jan 2021 in a single clinical center. The effect of surgical starting time (morning surgery vs afternoon surgery, day surgery vs night surgery) on elective CRC surgery was analyzed using propensity score matching (PSM). A total of 6783 patients were included in the current study. There were 5751 patients in day surgery group and 1032 patients in night surgery group, and there were 2920 patients in morning surgery group and 2831 patients in afternoon surgery group. After 1:1 ratio PSM, there were no significant difference in terms of the baseline information (P > .05). Day surgery group had longer operation time (P = .000) and longer hospital stay (P = .029) than night surgery group after PSM. Morning surgery group had longer operation time than afternoon surgery group before PSM (P = .000) and after PSM (P = .000). Univariate and multivariate analysis of the total of 6783 patients were conducted to find predictors of complications, and found that night surgery was a predictor of major complications (P = .002, OR = 1.763, 95% CI = 1.222-2.543) but not a predictor of overall complications (P = .250, OR = 1.096, 95% CI = 0.938-1.282). Night surgery is a predictor of major complications after elective CRC surgery, therefore, surgeons should be careful when operating at night.

Abstract
BACKGROUND Surgical start time (SST) has demonstrated conflicting effects on perioperative outcomes due to confounding factors, such as increased acuity in later SST cases. This study investigated the effect of SST on blood transfusion after gastric bypass surgery, a complication-prone elective surgical procedure. METHODS This retrospective cohort study included all patients undergoing gastric bypass surgery at a single academic medical center from 2016 through 2021 (n = 299). The primary independent variable was SST (before vs. after 15:00). The primary outcome was blood transfusion. Secondary outcomes included postoperative respiratory failure, length of stay, acute kidney injury, and mortality. The associations between SST and outcomes were investigated with univariate analyses. Multivariate and receiver operating characteristic (ROC) analyses were applied to the primary outcome, adjusting for demographic and operative characteristics. RESULTS On univariate analysis, 15:00-18:43 SST was associated with an increased risk of blood transfusion (relative risk 4.32, 95% confidence interval 1.27 to 14.63, p = 0.032), but not postoperative respiratory failure, acute kidney injury, length of stay, or mortality. On multivariate analysis, the only independent predictor of postoperative blood transfusion was a 15:00-18:43 SST (adjusted odds ratio 4.32, 95% confidence interval 1.06 to 15.96, c-statistic = 0.638). ROC analysis demonstrated that compared to the 15:00 threshold, a 14:34 threshold predicted postoperative blood transfusion with better accuracy (sensitivity = 70.0%, specificity = 83.0%). CONCLUSIONS Despite having similar demographic and operative characteristics, gastric bypass patients in the late SST cohort had a greater incidence of postoperative blood transfusion in this single-center study.

Abstract
Objective. The purpose of this study was to quantify the rate of adverse events associated to in neurosurgery interventions, to evaluate the differences in reporting of such events among different authors and reviews, and to find the reason behind the occurrence of this differences. Methods. A systematic literature review of scientific publications on existing classifications and reports of frequency on complications in neurosurgery was performed by analysing articles from international databases. Results and conclusion. This current overview is taking an outlook on the existing issues in the classification and reporting of complications in neurosurgery. Complications are common in neurosurgery. Because of nonuniform criteria, unstandardized data gathering procedures, and retrospective data collection, their reporting is inconsistent and varies considerably among authors and reviews. The best way to address this issue is by gathering prospective, multi-institutional outcomes data on neurosurgical patients. The data collection initiatives in the future should be using same terminology and be based on the same universally accepted criteria.

Abstract
OBJECTIVES To evaluate possible risk factors for complications following primary hypospadias repair relative to factors associated with timing of hypospadias repair in terms of case order, morning or afternoon scheduling, perioperative delays, and surgeon's daily work schedule as well as individual operative techniques. METHODS We retrospectively reviewed charts of 422 boys undergoing primary hypospadias repair with a sutured urethroplasty by one of three surgeons over a 10-year period and the surgeon's daily schedule. RESULTS The median age and IQR of the patients at time of operation was 0.79 (0.57) years, and median follow-up was 259 (664) days. A significant increase in the rate of any complication was noted with morning versus afternoon cases for the group overall with morning cases having a hazard 2.3 times higher than afternoon cases (p=0.012). Additionally, there was a significant increase in hazard of complication with increasing difference in time between actual procedure duration versus scheduled duration, with hazard of complication increasing 5% for each increase of 15 minutes of surgical time (p=.043). CONCLUSIONS A variety of previously identified potential risk factors for hypospadias complications were identified. Our analysis also demonstrated variability in level of risk of different factors between surgeons, reinforcing the utility of surgeons monitoring their own results in response to changes in technique. Novel potential risk factors for some surgeons identified in our study included an increased risk of complications when the hypospadias was done in the morning rather than the afternoon and when the procedure lasted longer than scheduled.

Lumbar decompression surgery for cauda equina syndrome - comparison of complication rates between daytime and overnight operating. Acta Neurochir (Wien) 2022; 164:1203-1208. [PMID: 35237869 DOI: 10.1007/s00701-022-05173-2] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2021] [Accepted: 12/16/2021] [Indexed: 11/24/2022]
Abstract
PURPOSE To investigate the incidence of complications from lumbar decompression ± discectomy surgery for cauda equina syndrome (CES), assessing whether time of day is associated with a change in the incidence of complications. METHODS Electronic clinical and operative notes for all lumbar decompression operations undertaken at our institution for CES over a 2-year time period were retrospectively reviewed. "Overnight" surgery was defined as any surgery occurring between 18:00 and 08:00 on any day. Clinicopathological characteristics, surgical technique, and peri/post-operative complications were recorded. Multivariable logistic regression was used to calculate odds ratios (OR) and 95% confidence intervals. RESULTS A total of 81 lumbar decompression operations were performed in the 2-year period and analysed. A total of 29 (36%) operations occurred overnight. Complete CES (CESR) was seen in 13 cases (16%) in total, 7 of whom underwent surgery during the day. Exactly 27 complications occurred in 24 (30%) patients. The most frequently occurring complication was a dural tear (n = 21, 26%), followed by post-operative haematoma, infection, and residual disc. Complication rates in the CESR cohort (54%) were significantly greater than in the CES incomplete (CESI) cohort (25%) (p = 0.04). On multivariable analysis, overnight surgery was independently associated with a significantly increased complication rate (OR 2.83, CI 1.02-7.89). CONCLUSIONS Lumbar decompressions performed overnight for CES were more than twice as likely to suffer a complication, in comparison to those performed within daytime hours. Our study suggests that out-of-hours operating, particularly at night, must be clinically justified and should not be influenced by day-time operating capacity.

Abstract
Objective The purpose of this study was to determine whether surgical scheduling affected patient outcomes following lumbar laminectomy. Physician fatigue caused by prolonged work hours has been shown to worsen outcomes. Previous research has also established a relationship between surgical scheduling and outcomes. Methods This was a retrospective chart review of single-level lumbar laminectomy patients at the Penn State Milton S. Hershey Medical Center between 1992 and 2019. Patients who underwent a one-level laminectomy between 1992 and 2019 were included in the study. Patients with procedures defined as complex (>1 level, tumor or abscess removal, discectomy, implant removal) were excluded. The surgical complication rate [cerebrospinal fluid (CSF) leak, 30-day redo, 30-day ED visit, weakness, sensation loss, infection, urinary retention] was compared across surgical start times, day of the week, proximity to a holiday, and procedure length. Results Procedures that started between 9:01-11:00 were more likely to have a complication than those between 7:01-9:00 (p=0.04). For every 60-min increase in surgery length, odds of having a complication increased by 2.01 times (p=0.0041). Surgeries that started between 11:01-13:00 had a significantly longer median surgery length than those between 7:01-9:00. Conclusion The time of the day when the procedure was started was predictive of worse outcomes following laminectomy. This may be attributed to several factors, including fatigue and staff turnover. Additionally, increased surgical length was predictive of more complications. It remains unclear whether increased surgical time results from correction of noticed errors or a fatigue-related decline in speed and performance. These findings on one-level laminectomy warrant further investigations since they have implications for reducing systemic failures that impact patient outcomes.

Abstract
OBJECTIVE To evaluate the influence of surgery start time (SST) and other patient- and therapy-related variables on the risk for early implant failure (EIF) in an academic setting. MATERIAL AND METHODS Data were extracted from the electronic health records of 61 patients who had at least one EIF and 140 age- and gender-matched, randomly selected, non-EIF controls. Bivariate and multivariable analyses were performed to identify relevant associations between EIF and different variables, such as SST. RESULTS Incidence of EIF was not significantly associated with SST (HR: 1.9 for afternoon implant placement, 95% CI: 0.9-3.9; p = .105). Other factors that were associated with a significantly increased risk for EIF in a multivariable model were pre-placement ridge augmentation (HR: 7.5, 95% CI: 2.2-25.1; p = .001), intra-operative complications (HR: 5.9, 95% CI: 2.2-16.3; p < .001), simultaneous soft tissue grafting (HR: 5.03, 95% CI: 1.3-19.5; p = .020), simultaneous bone grafting (HR: 3.7, 95% CI: 1.6-8.8; p = .002), and placement with sedation (HR: 3.4, 95% CI: 1.5-7.5; p = .002). CONCLUSIONS While SST was not associated with the occurrence of EIF in our cohort, other variables, such as ridge augmentation prior to implant placement, simultaneous bone or soft tissue grafting, intra-operative complications, implant placement with sedation, and number of implants in the oral cavity, were associated with an increased risk for this adverse event.

Abstract
STUDY DESIGN Retrospective analysis of clinical data from a single institution. OBJECTIVE The objective of this study was to assess the time of surgery as a possible predictor for outcomes, length of stay, and cost following microdiscectomy. SUMMARY OF BACKGROUND DATA The volume of microdiscectomy procedures has increased year over year, heightening interest in surgical outcomes. Previous investigations have demonstrated an association between time of procedures and clinical outcomes in various surgeries, however, no study has evaluated its influence on microdiscectomy. METHODS Demographic and outcome variables were collected from all patients that underwent a nonemergent microdiscectomy between 2008 and 2016. Patients were divided into 2 cohorts: those receiving surgery before 2 pm were assigned to the early group and those with procedures beginning after 2 pm were assigned to the late group. Outcomes and patient-level characteristics were compared using bivariate, multivariable logistic, and linear regression models. Adjusted length of stay and cost were coprimary outcomes. Secondary outcomes included operative complications, nonhome discharge, postoperative emergency department visits, or readmission rates. RESULTS Of the 1261 consecutive patients who met the inclusion criteria, 792 were assigned to the late group and 469 were assigned to the early group. There were no significant differences in demographics or baseline characteristics between the 2 cohorts. In the unadjusted analysis, mean length of stay was 1.80 (SD=1.82) days for the early group and 2.00 (SD=1.70) days for the late group (P=0.054). Mean direct cost for the early cohort was $5088 (SD=$4212) and $4986 (SD=$2988) for the late cohort (P=0.65). There was no difference in adjusted length of stay or direct cost. No statistically significant differences were found in operative complications, nonhome discharge, postoperative emergency department visits, or readmission rates between the 2 cohorts. CONCLUSION The study findings suggest that early compared with late surgery is not significantly predictive of surgical outcomes following microdiscectomy.

Abstract
Background The increase in the incidence of esophageal cancers (ECs) combined with fewer surgeons working at large centers will increase the likelihood of surgery for ECs being performed during later hours. This study aimed to compare esophagectomies’ operative outcomes for EC performed at different surgical starting times. Methods This was a single-center, retrospective study. Risk-adjusted cumulative sum curve analysis and Cox regression analysis were used to identify the potential change-point of surgical starting times. The participants were then divided into 2 groups according to the change-point time. Propensity score matching was used to control confounding factors between the 2 groups. We compared the short- and long-term outcomes in both groups. Results A total of 702 patients who underwent potentially radical esophagectomy from 7 May 2014 to 31 December 2017 in our institute were included. The 3-year all-cause mortality showed a significant change-point at 16:42, with an increment from 56.5% to 76.9% (P=0.043). Esophagectomy that commenced between 17:00–18:59 was associated with significantly lower overall survival (OS) [multivariate hazard ratio (HR): 2.47; 95% confidence interval (CI): 1.25 to 4.90; P=0.010] and disease-free survival (DFS) (multivariate HR: 2.14; 95% CI: 1.08 to 4.21; P=0.028). The participants were allocated to the during-hours group and the after-hours group according to the change-point of 17:00. A total of 84 participants in the during-hours group were matched to 33 participants in the after-hours group. The median operative time was shorter in the after-hours group [309 (during-hours) vs. 239 (after-hours) minutes, P=0.014); the after-hours group had a greater incidence of respiratory complications (22.63% vs. 45.45%, P=0.023) and 90-day mortality (0 vs. 9.09%, P=0.021). The 5-year OS (P=0.042) and DFS (P=0.030) were significantly higher in the during-hours group. Conclusions Esophagectomies started during after-hours are correlated with poorer surgical outcomes. It is recommended to cancel selective esophagectomies due to commence after 17:00.

Garba DL, Asher AM, Loewenstein J, Quinsey C. Does communication between neurosurgeons and anesthesiologists improve preoperative efficiency? Clin Neurol Neurosurg 2021; 201:106461. [PMID: 33508594 DOI: 10.1016/j.clineuro.2020.106461] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2020] [Revised: 10/02/2020] [Accepted: 12/27/2020] [Indexed: 10/22/2022]
Abstract
BACKGROUND Suboptimal communication can lead to preventable preoperative delays. In our study, we aimed to identify factors delaying surgery in the immediate preoperative period. Our outcomes of interest were the anesthesia release to incision time (RIT) and preoperative expectations of neurosurgery and anesthesia providers. Additionally, we introduced new communication goals prior to induction, to examine the impact on preoperative efficiency. METHODS The study is a prospective cohort analysis evaluating communication in the immediate preoperative period. In 42 consecutive cranial neurosurgical cases, a questionnaire was given to neurosurgical and anesthesia providers, and their responses were recorded. Halfway through this study, a formal pre-induction checklist was implemented that included expected duration of surgery, expected blood loss, surgical positioning, and intraoperative medication requirements. RESULTS Comparing the cohorts before and after implementing the checklist, no difference in release to incision time was observed. However, the difference in estimated procedure time was significantly decreased after implementation of the formal pre-induction checklist. Further, there was a trend towards better agreement in estimated blood loss, although results did not achieve statistical significance. These delays all demonstrated a statistically significant decrease after the new communication goals were executed. CONCLUSION While no statistically significant change in release to incision time was uncovered during our study, there was evidence that communication between teams improved after implementation of the checklist. Additionally, we observed less discrepancy in estimated case length and blood loss, suggesting focused communication goals aligned expectations of the neurosurgical and anesthesia teams.

Abstract
BackgroundSurgery at night (incision time 17:00 to 07:00 hours) may lead to increased postoperative mortality and morbidity. Mechanisms explaining this association remain unclear.MethodsWe conducted a multicentre retrospective cohort study of adult patients undergoing non-cardiac surgery with general anaesthesia at two major, competing tertiary care hospital networks. In primary analysis, we imputed missing data and determined whether exposure to night surgery affects 30-day mortality using a mixed-effects model with individual anaesthesia and surgical providers as random effects. Secondary outcomes were 30-day morbidity and the mediating effect of blood transfusion rates and provider handovers on the effect of night surgery on outcomes. We further tested for effect modification by surgical setting.ResultsAmong 350 235 participants in the primary imputed cohort, the mortality rate was 0.9% (n=2804/322 327) after day and 3.4% (n=940/27 908) after night surgery. Night surgery was associated with an increased risk of mortality (ORadj 1.26, 95% CI 1.15 to 1.38, p<0.001). In secondary analyses, night surgery was associated with increased morbidity (ORadj 1.41, 95% CI 1.33 to 1.48, p<0.001). The proportion of patients receiving intraoperative blood transfusion and anaesthesia handovers were higher during night-time, mediating 9.4% (95% CI 4.7% to 14.2%, p<0.001) of the effect of night surgery on 30-day mortality and 8.4% (95% CI 6.7% to 10.1%, p<0.001) of its effect on morbidity. The primary association was modified by the surgical setting (p-for-interaction<0.001), towards a greater effect in patients undergoing ambulatory/same-day surgery (ORadj 1.81, 95% CI 1.39 to 2.35) compared with inpatients (ORadj 1.17, 95% CI 1.02 to 1.34).ConclusionsNight surgery was associated with an increased risk of postoperative mortality and morbidity. The effect was independent of case acuity and was mediated by potentially preventable factors: higher blood transfusion rates and more frequent provider handovers.

Adult spinal deformity surgery: the effect of surgical start time on patient outcomes and cost of care. Spine Deform 2020; 8:1017-1023. [PMID: 32356281 DOI: 10.1007/s43390-020-00129-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/09/2020] [Accepted: 04/20/2020] [Indexed: 10/24/2022]
Abstract
PURPOSE There are reports investigating the effect of surgical start time (SST) on outcomes, length of stay (LOS) and cost in various surgical disciplines. However, this has not been studied in spine deformity surgery to date. This study compares outcomes for patients undergoing spinal deformity surgery based on SST. METHODS Patients at a single academic institution from 2008 to 2016 undergoing elective spinal deformity surgery (defined as fusing ≥ 7 segments) were divided by SST before or after 2 PM. Co-primary outcomes were LOS and direct costs. Secondary outcomes included delayed extubation, ICU stay, complications, reoperation, non-home discharge, and readmission rates. RESULTS There were 373 surgeries starting before 2 PM and 79 after 2 PM. The cohorts had similar demographics including age, sex, comorbidity burden, and levels fused. The late SST cohort had shorter operation durations (p = 0.0007). Multivariable linear regression showed no differences in LOS (estimate 0.4 days, CI - 1.2 to 2.0, p = 0.64) or direct cost (estimate $3652, 95% CI - $1449 to $8755, p = 0.16). Multivariable logistic regression revealed the late SST cohort was more likely to have delayed extubation (OR 2.6, 95% CI 1.4-4.9, p = 0.004) and non-home discharge (OR 2.2, 95% CI 1.1-4.2, p = 0.03). All other secondary outcomes were non-significant. CONCLUSION Patients undergoing spinal deformity surgery before and after 2 PM have similar LOS and cost of care. However, the late SST cohort had increased likelihood of delayed extubation and non-home discharges, which increase cost in bundled payment models. These findings can be utilized in OR scheduling to optimize outcomes and minimize cost.

Abstract
STUDY DESIGN Retrospective study of a surgical cohort from a single, large academic institution. OBJECTIVE The aim of this study was to investigate associations between surgical start time, length of stay, cost, perioperative outcomes, and readmission. SUMMARY OF BACKGROUND DATA One retrospective study with a smaller cohort investigated associations between surgical start time and outcomes in spine surgery and found that early start times were correlated with shorter length of stay. No examinations of perioperative outcomes or cost have been performed. METHODS All patients undergoing anterior cervical discectomy and fusion (ACDF) and posterior cervical decompression and fusion (PCDF) were queried from a single institution from January 1, 2008 to November 30, 2016. Patients undergoing surgery that started between 12:00 AM and 6:00 AM were excluded due to their likely emergent nature. Cases starting before and after 2:00 PM were compared on the basis of length of stay and cost as the primary outcomes using multivariable logistic regression. RESULT The patients undergoing ACDF and PCDF were both similar on the basis of comorbidity burden, preoperative diagnosis, and number of segments fused. The patients undergoing ACDF starting after 2 PM had longer LOS values (adjusted difference of 0.65 days; 95% confidence interval [CI]: 0.28-1.03; P = 0.0006) and higher costs of hospitalization (adjusted difference of $1177; 95% CI: $549-$1806; P = 0.0002). Patients undergoing PCDF starting after 2 PM also had longer LOS values (adjusted difference of 1.19 days; 95% CI: 0.46-1.91; P = 0.001) and higher costs of hospitalization (adjusted difference of $2305; 95% CI: $826-$3785; P = 0.002). CONCLUSION Later surgical start time is associated with longer LOS and higher cost. These findings should be further confirmed in the spine surgical literature to investigate surgical start time as a potential cost-saving measure. LEVEL OF EVIDENCE 3.

Abstract
Gastric cancer (GC) continues to be 1 of the malignant tumors with high morbidity and mortality worldwide. Although the improvements in targeted inhibitor therapy have promoted survival, the first choice for GC patients is still surgery. However, prolonged surgery may tire surgeons and affect surgical outcomes.To detect whether different time-of-day radical gastrectomy influenced short-term and long-term surgical outcomes.This study included 117 patients between 2008 and 2012 who underwent a radical gastrectomy. These patients were grouped into the morning (before 13:00) and afternoon (after 13:00) groups or divided into 2 groups according to the median operation start time (before or after 11:23). Then, the relevant influence of the surgical start time was analyzed.The morning group (before 13:00) and the front median group (before 11:23) showed longer operative time (P = .008 and P = .016, respectively), lower estimated blood loss (P < .001 and P = .158, respectively), and longer time before resuming oral intake (P < .001 and P < .173, respectively) than the afternoon group (after 13:00) or latter median group (after 11:23). Starting the operation in the morning had no effect on the rate of postoperative complications. The operation start time had no significant influence on the overall survival of patients who underwent a radical gastrectomy. However, in subgroup analysis, patients who underwent a distal gastrectomy faced poor prognosis when their surgery started after 13:00 (P = .030).The results suggest that the operation start time might be an indicator of total operative time, estimated blood loss, and the time to resuming oral intake. The operation start time may also influence the prognosis of radical gastrectomy in patients with GC.

Abstract
OBJECTIVE The after-hours effect on postoperative complications has been poorly studied in the neurosurgical literature. A recent retrospective analysis showed that patients with a surgical start time (SST) between 09:01 pm and 07:00 am had a greater risk of complications. This study used a prospective registry to examine the relationship between SST and postoperative complications in a large neurosurgical population. METHODS We performed a prospective longitudinal cohort analysis of all consecutive adult patients admitted to our neurosurgery service between October 1, 2018 and May 1, 2019. Complications were prospectively recorded and classified as surgical or medical. Univariate and multivariate logistic regressions were used to analyze these data. RESULTS Eighty-five surgical complications (6.6%) and 110 medical complications (8.6%) resulted from 1285 operations on 1145 patients. Later SST was predictive of complications in the emergent population (odds ratio [OR], 2.28; 95% confidence interval [CI], 1.01-5.15; P = 0.048) but not in the elective population. Extubation in the neurosurgical intensive care unit (NICU) versus the operating room strongly predicted medical complications (OR, 6.91; 95% CI, 3.33-14.34; P < 0.0001). Patients with a later SST were significantly more likely to be extubated in the NICU (P < 0.0001). CONCLUSIONS Patients undergoing emergent operations with a later SST were significantly more likely to have a postoperative complication. Patients who were extubated in the NICU versus the operating room were significantly more likely to have a medical complication. Patients were more likely to be extubated in the NICU if they had a later SST; therefore, SST may indirectly be associated with an increase in medical complications.

Abstract
OBJECTIVE It is unknown what proportion of patients who undergo emergent neurosurgical procedures initiate comfort care (CC) measures shortly after the operation. The purpose of the present study was to analyze the proportion and predictive factors of patients who initiated CC measures within the same hospital admission after undergoing emergent neurosurgery. METHODS This retrospective cohort study included all adult patients who underwent emergent neurosurgical and endovascular procedures at a single center between 2009 and 2014. Primary and secondary outcomes were initiation of CC measures during the initial hospitalization and determination of predictive factors, respectively. RESULTS Of the 1295 operations, comfort care was initiated in 111 (8.6%) during the initial admission. On average, CC was initiated 9.3 ± 10.0 days postoperatively. One-third of the patients switched to CC within 3 days. In multivariate analysis, patients > 70 years of age were significantly more likely to undergo CC than those < 50 years (70-79 years, p = 0.004; > 80 years, p = 0.0001). Two-thirds of CC patients had been admitted with a cerebrovascular pathology (p < 0.001). Admission diagnosis of cerebrovascular pathology was a significant predictor of initiating CC (p < 0.0001). A high Hunt and Hess grade of IV or V in patients with subarachnoid hemorrhage was significantly associated with initiation of CC compared to a low grade (27.1% vs 2.9%, p < 0.001). Surgery starting between 15:01 and 06:59 hours had a 1.70 times greater odds of initiating CC compared to surgery between 07:00 and 15:00. CONCLUSIONS Initiation of CC after emergent neurosurgical and endovascular procedures is relatively common, particularly when an elderly patient presents with a cerebrovascular pathology after typical operating hours.

Abstract
Objective: To determine the association between intraday timing of outpatient pediatric tonsillectomy and revisit outcomes and complications. Study Design: Cross-sectional analysis of New York databases. Setting: Ambulatory surgery, emergency department and inpatient hospital settings. Subjects and Methods: The State Ambulatory Surgery, State Emergency Department and State Inpatient Databases for 2010-2011 were analyzed for revisits. Outcomes assessed were revisits for any reason, bleeding, acute pain or fever, nausea, vomiting and dehydration. The relationships between the hour of admission for surgery, the hour of discharge and the revisit outcomes were analyzed. Results: The study included 33,611 children (mean age, 6.62 years; 45.7% female) and 62.0% were admitted in the early morning. Discharges were most common in the early afternoon (28.3%). Revisit rates were significantly higher for the early evening discharges (6.0%) versus late morning discharges (3.1%) ( P < .001). Revisits for bleeding were 1.8% for discharge in the early evening versus 0.6% in the late morning ( P < .001). Revisits for fever, nausea, vomiting or dehydration were 1.8% for discharge in the early evening versus 0.9% in the late morning ( P = .002). Late afternoon admission was significantly associated with higher revisit rates (10.9%, P < .001). Bleeding revisits were highest for late afternoon admit hour (1.5%, P = .001). Revisits for acute pain were also highest for late afternoon admit hour (2.3%, P = .005). Conclusion: Revisit are significantly higher when the patient is discharged late. Late afternoon surgery is also significantly associated with higher revisit rates. Surgeons may wish to consider these findings when a late tonsillectomy or late discharge is anticipated post-tonsillectomy.

Abstract
Introduction: Neurosurgical residency training is costly, with expenses largely borne by the academic institutions that train residents. One expense is increased operative duration, which leads to poorer patient outcomes. Although other studies have assessed the effect of one resident assisting, none have investigated two residents; thus, we sought to investigate if two residents versus one scrubbed-in impacted operative time, estimated blood loss (EBL), and length-of-stay (LOS).Methods: In this retrospective review of patients who underwent a neurosurgical procedure involving one or two residents between January 2013 and April 2016, we performed multivariable linear regression to determine if there was an association between resident participation and case length, operating room time, EBL, and LOS. We also included patient demographics, attending surgeon, day of the week, start time, pre-operative LOS, procedure performed, and other variables in our model. Only procedures performed at least 40 times during the study period were analyzed.Results: Of 860 procedures that met study criteria, 492 operations were one of six procedures performed at least 40 times, which were anterior cervical discectomy and fusion, cerebrospinal fluid (CSF) shunt insertion, CSF shunt revision, lumbar laminectomy, intracranial hematoma evacuation, and non-skull base, supratentorial parenchymal brain tumor resection. An additional resident was associated with a 35.1-min decrease (p = .01) in operative duration for lumbar laminectomies. However, for intracranial hematoma evacuations, an extra resident was associated with a 24.1 min increase (p = .03) in procedural length. There were no significant differences observed in the other four surgeries.Conclusion: An additional resident may lengthen duration of intracranial hematoma evacuations. However, two residents scrubbed-in were associated with decreased lumbar laminectomy duration. Overall, an extra resident does not increase procedural duration, total operating room utilization, EBL, or post-operative LOS. Allowing two residents to scrub in may be a safe and cost-effective method of educating neurosurgical residents.

Abstract
BACKGROUND The aim of this post hoc analysis of a large cohort study was to evaluate the association between night-time surgery and the occurrence of intraoperative adverse events (AEs) and postoperative pulmonary complications (PPCs). METHODS LAS VEGAS (Local Assessment of Ventilatory Management During General Anesthesia for Surgery) was a prospective international 1-week study that enrolled adult patients undergoing surgical procedures with general anaesthesia and mechanical ventilation in 146 hospitals across 29 countries. Surgeries were defined as occurring during 'daytime' when induction of anaesthesia was between 8:00 AM and 7:59 PM, and as 'night-time' when induction was between 8:00 PM and 7:59 AM. RESULTS Of 9861 included patients, 555 (5.6%) underwent surgery during night-time. The proportion of patients who developed intraoperative AEs was higher during night-time surgery in unmatched (43.6% vs 34.1%; P<0.001) and propensity-matched analyses (43.7% vs 36.8%; P=0.029). PPCs also occurred more often in patients who underwent night-time surgery (14% vs 10%; P=0.004) in an unmatched cohort analysis, although not in a propensity-matched analysis (13.8% vs 11.8%; P=0.39). In a multivariable regression model, including patient characteristics and types of surgery and anaesthesia, night-time surgery was independently associated with a higher incidence of intraoperative AEs (odds ratio: 1.44; 95% confidence interval: 1.09-1.90; P=0.01), but not with a higher incidence of PPCs (odds ratio: 1.32; 95% confidence interval: 0.89-1.90; P=0.15). CONCLUSIONS Intraoperative adverse events and postoperative pulmonary complications occurred more often in patients undergoing night-time surgery. Imbalances in patients' clinical characteristics, types of surgery, and intraoperative management at night-time partially explained the higher incidence of postoperative pulmonary complications, but not the higher incidence of adverse events.

Abstract
BACKGROUND Pediatric neurosurgeons are occasionally tasked with performing surgery expeditiously to preserve a child's neurologic faculties and life. OBJECTIVE This study examines the etiologies, outcomes, and costs for urgent or emergent craniotomies at a Level I Pediatric Trauma center over a 7-year time period. METHODS A retrospective review was conducted for each patient who underwent an emergent or urgent craniotomy within 24 hours of presentation between January 2010 and April 2017. Demographic, clinical, and surgical details were recorded for a total of 48 variables. Any readmission within 90 days was analyzed. Hospital charges for each admission and readmission were collected and adjusted for inflation to October 2018 values. RESULTS Among the 223 children who underwent urgent or emergent craniotomies, the majority were admitted for traumatic injuries (n = 163, 73.1%). The most common traumatic mechanism was fall (n = 51, 22.9%), and the most common non-traumatic cause was tumor (n = 21, 9.4%). Overall, craniotomies were typically performed for hematoma evacuation of one type or combination (n = 115, 51.6%) during off-peak times (n = 178, 79.8%). Seventy-seven (34.5%) subjects experienced 1 or more postoperative events, 22 of whom returned to the operating room. There were 13 (5.8%) and 33 (14.8%) readmissions within 30 days and 90 days of discharge, respectively. Non-trauma patients (compared with trauma patients) and polytrauma (compared with isolated head injury) had greater healthcare needs, resulting in higher charges. CONCLUSION Most urgent or emergent pediatric craniotomies were performed for the treatment of traumatic injuries involving hematoma evacuation, but non-traumatic patients were more complex requiring greater resources.

Abstract
INTRODUCTION To evaluate the adverse event rate following pars plana vitrectomy as a function of surgical start time and the presence of a vitreoretinal fellow. METHODS Single-institution retrospective cohort study of patients undergoing pars plana vitrectomy from 1 January 2016 to 31 December 2016 at Stanford University School of Medicine (Palo Alto, CA, USA). Records were reviewed for surgical start time, the presence of vitreoretinal fellow, and postoperative adverse events defined as any finding deviating from the expected postoperative course requiring observation or intervention. RESULTS A total of 310 pars plana vitrectomies were performed. There was no statistical difference in the rate of any adverse event when comparing cases starting after 16:01 (9/13, 69.2%) and after 12:01 (42/99, 42.4%) to a morning start time (69/198, 34.9%, adjusted p = 0.083). There was a statistically significant increase in the risk of postoperative vitreous hemorrhage with afternoon and evening cases as compared to morning cases (adjusted p = 0.021). In addition, there was no difference in any adverse event with a fellow present (93/244, 38.1%) compared to without (27/66, 40.9%, adjusted p = 0.163). There was a higher risk of postoperative hypotony when a fellow was involved (6.6% vs 0%, p = 0.028), though this difference disappeared after adjusting for confounders (adjusted p = 0.252). There was no difference in the length of surgery with and without a fellow (49 vs 54 min, respectively; p = 0.990). DISCUSSION Afternoon start time and the presence of a fellow were not independent risk factors for postoperative adverse events.
