Association of Anesthesia Duration With Complications After Microvascular Reconstruction of the Head and Neck.

ABSTRACT:

Importance

Prolonged anesthesia and operative times have deleterious effects on surgical outcomes in a variety of procedures. However, data regarding the influence of anesthesia duration on microvascular reconstruction of the head and neck are lacking.

Objective

To examine the association of anesthesia duration with complications after microvascular reconstruction of the head and neck.

Design, setting, and participants

The American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database was used to collect data. In total, 630 patients who underwent head and neck microvascular reconstruction were recorded in the NSQIP registry from January 1, 2005, through December 31, 2013. Patients who underwent microvascular reconstructive surgery performed by otolaryngologists or plastic surgeons were included in this study. Data analysis was performed from October 15, 2015, to January 15, 2016.

Exposures

Microvascular reconstructive surgery of the head and neck.

Main outcomes and measures

Patients were stratified into 5 quintiles based on mean anesthesia duration and analyzed for patient characteristics and operative variables (mean [SD] anesthesia time: group 1, 358.1 [175.6] minutes; group 2, 563.2 [27.3] minutes; group 3, 648.9 [24.0] minutes; group 4, 736.5 [26.3] minutes; and group 5, 922.1 [128.1] minutes). Main outcomes include rates of postoperative medical and surgical complications and mortality.

Results

A total of 630 patients undergoing head and neck free flap surgery had available data on anesthesia duration and were included (mean [SD] age, 61.6 [13.8] years; 436 [69.3%] male). Bivariate analysis revealed that increasing anesthesia duration was associated with increased 30-day complications overall (55 [43.7%] in group 1 vs 80 [63.5%] in group 5, P = .006), increased 30-day postoperative surgical complications overall (45 [35.7%] in group 1 vs 78 [61.9%] in group 5, P < .001), increased rates of postoperative transfusion (32 [25.4%] in group 1 vs 70 [55.6%] in group 5, P < .001), and increased rates of wound disruption (0 in group 1 vs 10 [7.9%] in group 5, P = .02). No specific medical complications and no overall medical complication rate (24 [19.0%] in group 1 vs 22 [17.5%] in group 5, P = .80) or mortality (1 [0.8%] in group 1 vs 1 [0.8%] in group 5, P = .75) were associated with increased anesthesia duration. On multivariate analysis accounting for demographics and significant preoperative factors including free flap type, overall complications (group 5: odds ratio [OR], 1.98; 95% CI, 1.10-3.58; P = .02), surgical complications (group 5: OR, 2.46; 95% CI, 1.35-4.46; P = .003), and postoperative transfusion (group 5: OR, 2.31; 95% CI, 1.27-4.20; P = .006) remained significantly associated with increased anesthesia duration; the association of wound disruption and increased anasthesia duration was nonsignificant (group 5: OR, 2.0; 95% CI, 0.75-5.31; P = .16).

Conclusions and relevance

Increasing anesthesia duration was associated with significantly increased rates of surgical complications, especially the requirement for postoperative transfusion. Rates of medical complications were not significantly altered, and overall mortality remained unaffected. Avoidance of excessive blood loss and prolonged anesthesia time should be the goal when performing head and neck free flap surgery.

Project description:ImportanceFree flap surgery is a lengthy procedure with massive tissue destruction and reconstruction, which makes postoperative pulmonary complications (PPCs) a noticeable issue among patients with head and neck cancer. Propofol-based total intravenous anesthesia (TIVA) has better survival outcomes than inhalational anesthesia (INH) in several types of cancer surgery. A previous retrospective study found that patients in the TIVA group had a lower PPC rate, which may be correlated with a lower intraoperative fluid requirement. We hypothesize that the protective effect remains among patients undergoing free flap surgery for head and neck cancer in a prospective and goal-directed fluid therapy setting.ObjectiveTo assess the effect of TIVA vs INH on PPCs in patients undergoing microvascular reconstruction for head and neck cancer.Design, setting, and participantsThis prospective, 2-arm, randomized clinical trial was conducted at a tertiary hospital in Taiwan; a total of 78 patients 18 years and older with American Society of Anesthesiologists physical status classification 1 to 3 who were scheduled for elective free flap surgery under general anesthesia were included. The trial started in October 2017, completed in October 2019, and finished analysis in January 2022.InterventionsPatients were enrolled and randomized to the TIVA or INH group. All patients received goal-directed fluid therapy and hemodynamic management if they had a mean arterial pressure (MAP) below 75 mm Hg or a reduction of 10% from baseline MAP.Main outcomes and measuresThe primary outcome was a composite of PPCs. The secondary outcomes were the differences in intraoperative hemodynamic values (mean arterial pressure, MAP; cardiac index, CI; systemic vascular resistance index, SVRI; and stroke volume variation, SVV).ResultsA total of 70 patients (65 men [93%]; 5 women [7%]) completed the trial; median (IQR) age was 52.0 (48-59) years in the TIVA group and 57.0 (46-64) years in the INH group. The demographic characteristics were similar between the 2 groups, except that patients in the TIVA group had a slightly lower body mass index. Patients in the TIVA group had a lower risk of developing PPCs (unadjusted odds ratio, 0.25; 95% CI, 0.08-0.80). The TIVA group had significantly higher MAP, lower CI, and higher SVRI than the INH group after the third hour of monitoring. The TIVA group showed a relatively stable hourly MAP, CI, SVRI, and SVV across time points, while the INH group showed a more varying pattern. The generalized estimating equation showed no clinical differences in the trend of hemodynamic parameters across time between groups.Conclusions and relevanceIn this randomized clinical trial, using propofol-based TIVA reduced the incidence of PPCs in free flap surgery. This finding may be related to more stable hemodynamic manifestations and a lower total balance of fluid throughout the surgery.Trial registrationClinicalTrials.gov Identifier: NCT03263078.

Project description:ImportanceBecause microvascular free flap reconstruction is increasingly used to restore function in patients with head and neck cancer, there is a growing need for evidence-based perioperative care.ObjectiveTo assess the association of different team-based surgical approaches with intraoperative and postoperative outcomes for patients undergoing head and neck free flap reconstruction.Design, setting, and participantsThis retrospective cohort study of 733 patients was conducted at an academic tertiary care medical center. Head and neck oncologic procedures involving microvascular free flap reconstruction with available intraoperative data collected from January 1, 2000, to December 31, 2021, were included.Main outcomes and measuresPatient characteristics including demographic characteristics and comorbid conditions, operative variables, length of stay, and postoperative outcomes were measured. Descriptive statistics and effect size measures were performed to compare the 3 intraoperative surgical team approaches, specifically single surgeon, separate 2-team approach, and integrated 2-team approach; 1:1 nearest neighbor matching without caliper was performed to compare single- vs 2-team and separate and integrated 2-team approaches. Effect size measures including Cramer V for dichotomous variables, the Kendall W coefficient of concordance for ordinal variables, and η2 for continuous variables were reported with 95% CIs to describe precision.ResultsAmong 733 cases, there were no clinically significant differences in patient demographic characteristics, clinicopathologic characteristics, and choice of free flap reconstruction based on intraoperative surgical team approach. The mean (SD) age was 58.7 (12.4) years, and 514 were male (70.1%). In terms of operative and postoperative variables, there was a difference in operative times and intraoperative fluid requirements among the 3 different techniques, with the integrated 2-team approach demonstrating a mean reduction in operative time of approximately 2 hours (η2 = 0.871; 95% CI, 0.852-0.887; mean [SD] operative time = 541 [191] minutes for the single-surgeon approach, 399 [175] minutes for the integrated 2-team approach, and 537 [200] minutes for the separate 2-team approach) and lower fluid requirements of greater than 1 L (η2 = 0.790; 95% CI, 0.762-0.817). In both unadjusted analyses and propensity score matching, there were no clinically significant differences in terms of ischemia time, use of pressors, postoperative complications (including free flap failure, number of return trips to the operating room, length of stay, or 30-day readmission) based on intraoperative team approach.Conclusions and relevanceFindings suggest that the integrated 2-team surgical approach for complex head and neck microvascular reconstruction can be used to safely decrease operative time, with no difference in postoperative outcomes.

Project description:ImportanceAesthetic outcomes are key determinants of psychosocial functioning among surgically treated patients with head and neck cancer (HNC); however, long-term aesthetic outcomes after microvascular free tissue transfer (MFTT) are not well described.ObjectiveTo examine risk factors for impaired long-term aesthetic satisfaction and appearance-related psychosocial functioning after HNC ablation with MFTT.Design, setting, and participantsA cross-sectional, web-based survey was conducted at an academic tertiary care center. A total of 228 individuals who underwent MFTT between January 1, 2015, and December 31, 2019, for treatment of HNC were included. The study was conducted from November 1, 2020, through January 15, 2021.ExposuresHead and neck cancer ablation with MFTT.Main outcomes and measuresPatient-reported outcomes were assessed via Aesthetic FACE-Q scales. The primary objective was aesthetic satisfaction determined by the Satisfaction With Facial Appearance scale. Secondarily, the Appearance-Related Psychosocial Distress, Psychological Function, and Social Function scales were used to assess appearance-related psychosocial functioning. Patients were stratified by demographic, disease, surgical, and postoperative characteristics. Survey scores on a 100-point scale were compared and subjected to univariable and multivariable linear regression.ResultsA total of 124 of 228 patients (54.4%) completed surveys a median of 34.4 months after MFTT (interquartile range, 22.6-48.8). Most responders (79 [63.7%]) were men with advanced cancer of the oral cavity or skin, reconstructed with anterolateral thigh or osteocutaneous fibula free flaps. Nonresponders had no significant differences in baseline characteristics. The Satisfaction With Facial Appearance score was independently lower among patients who received osteocutaneous flaps (regression coefficient, -10.6 points, 95% CI, -20.4 to -0.8 points) and/or adjuvant (chemo)radiotherapy (regression coefficient, -6.9 points; 95% CI, -13.8 to -0.1 points). Impaired appearance-related psychosocial functioning was independently associated with female sex, a history of anxiety or depression, osteocutaneous flaps, prolonged tube feeding requirements, and any recurrent or persistent disease. After adjustment for covariates, each 1-point increase in the Satisfaction With Facial Appearance score independently estimated improved appearance-related psychosocial functioning as determined by the Appearance-Related Psychosocial Distress scale (regression coefficient, -0.5 points; 95% CI, -0.7 to -0.4 points), Psychological Function scale (regression coefficient, 0.4 points; 95% CI, 0.3 to 0.5 points), and Social Function scale (regression coefficient, 0.4 points; 95% CI, 0.3 to 0.6 points).Conclusions and relevanceThe findings of this cross-sectional, web-based survey study suggest that osteocutaneous reconstruction and adjuvant therapy independently increase the risk of poor patient-reported long-term aesthetic satisfaction, which correlated with impaired appearance-related psychosocial functioning. Aesthetic outcomes appear to be a priority to address in patients with HNC undergoing MFTT.
