COMPARISON OF EFFICACY BETWEEN DEXMEDETOMIDINE AND PROPOFOL AFTER CORONARY ARTERY BYPASS GRAFT SURGERY

Postoperative management following coronary artery bypass graft (CABG) surgery is crucial for patient outcomes. Sedation plays a key role in recovery, with dexmedetomidine and propofol being commonly used agents. Evaluating the efficacy of these sedatives can help optimise postoperative care. Objective: To compare the effectiveness of dexmedetomidine and propofol in terms of pulmonary complications, mean mechanical ventilation time, and postoperative ICU and hospital stay in patients undergoing CABG surgery. Methods: A randomised controlled trial was conducted from October 1, 2023, to December 31, 2023, at a tertiary care hospital. Eighty patients scheduled for CABG surgery were randomised into two groups: Group A received dexmedetomidine, and Group B received propofol. Outcomes were assessed by measuring the incidence of pulmonary complications, mean mechanical ventilation time, length of postoperative ICU stay, and total hospital stay. Statistical analysis was performed using appropriate tests to compare the outcomes between the two groups, with significance set at P < 0.05. Results: Pulmonary complications occurred in 5% of patients in Group A, significantly lower than the 20% observed in Group B (P = 0.04). Group A's mean mechanical ventilation time was 17.03 ± 3.46 hours, considerably shorter than Group B's 23.20 ± 5.55 hours (P = 0.0001). Group A's average postoperative ICU stay was 62.53 ± 15.10 hours, notably less than the 71.10 ± 14.06 hours for Group B (P = 0.01). Additionally, the mean hospital stay in Group A was 20.60 ± 1.99 days, significantly shorter than the 21.85 ± 3.11 days in Group B (P = 0.03). Conclusion: Dexmedetomidine demonstrates superior efficacy to propofol for patients undergoing CABG surgery, as evidenced by reduced pulmonary complications, shorter mechanical ventilation duration, and decreased postoperative ICU and hospital stays.

Association between mechanical power during one-lung ventilation and pulmonary complications after thoracoscopic lung resection surgery: a prospective observational study

BackgroundThe role of mechanical power on pulmonary outcomes after thoracic surgery with one-lung ventilation was unclear. We investigated the association between mechanical power and postoperative pulmonary complications in patients undergoing thoracoscopic lung resection surgery.MethodsIn this single-center, prospective observational study, 622 patients scheduled for thoracoscopic lung resection surgery were included. Volume control mode with lung protective ventilation strategies were implemented in all participants. The primary endpoint was a composite of postoperative pulmonary complications during hospital stay. Multivariable logistic regression models were used to evaluate the association between mechanical power and outcomes.ResultsThe incidence of pulmonary complications after surgery during hospital stay was 24.6% (150 of 609 patients). The multivariable analysis showed that there was no link between mechanical power and postoperative pulmonary complications.ConclusionsIn patients undergoing thoracoscopic lung resection with standardized lung-protective ventilation, no association was found between mechanical power and postoperative pulmonary complications.Trial registrationTrial registration number: ChiCTR2200058528, date of registration: April 10, 2022.

The impact of goal-directed fluid therapy on postoperative pulmonary complications in patients undergoing thoracic surgery: a systematic review and meta-analysis.

Pulmonary complications after thoracic surgery are common and associated with significant morbidity and high cost of care. Goal-directed fluid therapy (GDFT) could reduce the incidence of postoperative pulmonary complications (PPCs) and facilitate recovery in patients undergoing major abdominal surgery. However, whether GDFT could reduce the incidence of PPCs in patients undergoing thoracic surgery was unclear. The present meta-analysis was designed to assess the impact of Goal-directed Fluid Therapy on PPCs in patients undergoing thoracic surgery. Randomized controlled trials (RCTs) comparing GDFT with other conventional fluid management strategies in adult patients undergoing thoracic surgery were identified. Databases searched included PubMed, Web of Science, Embase, and Cochrane Library databases. Review Manager 5.4 (The Cochrane Collaboration, Oxford, UK) software was used for statistical analysis. Heterogeneity was analyzed using I2 statistics, and a standardized mean difference with 95% CI and P value was used to calculate the treatment effect for outcome variables. The primary study outcomes were the incidence of PPCs. Secondary outcomes were the total volume infused, the length of hospitalization, the incidence of cardiac complications, and the incidence of renal dysfunction. Subgroup analysis was planned to verify the definite role of GDFT. A total of 6 RCTs consisting of 680 patients were included in this meta-analysis, which revealed that GDFT did not reduce the incidence of PPCs in patients undergoing thoracic surgery (RR, 0.57; 95% CI 0.29-1.14). However, GDFT decreased the total intra-operative fluid input (MD, - 244.40ml; 95% CI - 397.06 to - 91.74). There was no statistical difference in the duration of hospitalization (MD; - 1.31, 95% CI - 3.00 to 0.38), incidence of renal dysfunction (RR, 0.62; 95% CI 0.29-1.35), and incidence of cardiac complications (RR, 0.62; 95% CI 0.27-1.40). The results of this meta-analysis indicate that GDFT did not reduce the postoperative incidence of pulmonary complications in individuals undergoing thoracic surgery. However, considering the small number of contributing studies, these results should be interpreted with caution.

Effects of Early Mobilisation on Post Operative Pulmonary Complication in Patients with Open Abdominal Surgery

Background: Patients undergoing open abdominal surgery are the focus of this research, namely the effect of earlymobilisation on postoperative pulmonary problems. Early mobilization is proposed as a potential intervention toenhance respiratory function and reduce the risk of PPCs.Purpose: The purpose of this study is to evaluate the impact of pre-operative mobilisation on the incidence ofpulmonary complications in patients undergoing open abdominal surgery.Materials and Methods: This quasi-experimental study included 50 subjects who underwent open abdominalsurgery at Saveetha Medical Hospital, SIMTS. Convenient sampling was used to select the participants. Measuresof oxygen saturation (SPO2) and pulmonary function (FEV1) from a spirometer were employed as functionaloutcome indicators. After two weeks, participants were given a post-test to record their progress.Results: Data collected before and after early mobilisation exercise were analysed using a paired t-test. Theexperimental group showed significant improvements in SPO2, FIM, and FEV1 (P<0.0001), indicating highervalues post-intervention. Post-test demonstrated higher statistical significance compared to pre-test.Conclusion: As a result, it was shown that early mobilisation Exercise is beneficial for reducing pulmonarycomplications after surgery.

Postoperative pulmonary complications in awake video-assisted thoracoscopic surgery: Our 10-year experience.

The aim of this study was to evaluate the effect of awake video-assisted thoracoscopic surgery on postoperative pulmonary complications among patients with different risk scores using the Assess Respiratory Risk in Surgical Patients in Catalonia (ARISCAT). Between January 2011 and August 2021, a total of 246 patients (158 males, 88 females; mean age: 59.1±13.6 years; range, 25 to 84 years) who underwent awake video-assisted thoracoscopic surgery were retrospectively analyzed. According to the ARISCAT scores, the patients with low and intermediate scores were included in Group L (n=173), while those with high scores (n=73) were included in Group H. Sedation protocol consisted of the combination of midazolam and fentanyl with propofol infusion, if necessary. Oxygen was delivered via face mask or nasal canula (2 to 5 L/min) maintaining an oxygen saturation of >95%, and analgesia was achieved with intercostal nerve block. Demographics, operative, and postoperative data of the patients, and pulmonary complications were evaluated. Demographics, operative, and postoperative data were similar between the groups. Postoperative pulmonary complications were observed in 20 (27%) patients in Group H and 29 (17%) patients in Group L without statistically significant difference (p=0.056). Surgical approaches consisted of pleural procedures (n=194) and pulmonary resection (n=52). The incidence of pulmonary complications was significantly higher in the pulmonary resection compared to non-pulmonary procedures (p=0.027). Awake video-assisted thoracoscopic surgery seems to be beneficial in reducing the incidence of postoperative pulmonary complications in high-risk patients as assessed with the ARISCAT.

Optimization of lung ultrasound in ultrafast-track anesthesia for non-cyanotic congenital heart disease surgery

ObjectiveWe aimed to explore the feasibility of lung ultrasound for perioperative assessment and the optimal effect of lung ultrasound in reducing lung complications during non-cyanotic congenital heart disease (CHD) surgery using ultrafast-track anesthesia. MethodsSixty patients were treated at Shenzhen Children's Hospital between 2019 and 2020. Of these, 30 patients in group N had an indication for extubation and ultrafast-track anesthesia after congenital heart surgery; the tracheal catheter was removed, and the patients were sent to the cardiac intensive care unit (CICU) for further monitoring and treatment. Another 30 patients were in group L and also had an indication for extubation and ultrafast-track anesthesia; in addition we compared lung ultrasound score (LUS) before and after surgery, when we found the cases that LUS ≥ 15, for whom targeted optimization treatment would be carried out. The tracheal catheter was removed after LUS <15 days before the patients were sent to the CICU. In all cases, the LUS and PaO2/FiO2 ratios (P/F) of both groups were recorded at the time of anesthesia induction (T0), before extubation (T1), and 5 min (T2), 1 h (T3), and 24 h (T4) after extubation. The incidence of pulmonary complications, LUS, and P/F were compared between the two groups. ResultsThere was great consistency between LUS and radiographic findings. Comparing the data of the two groups at T2, T3 and T4, the P/F was higher and the LUS was lower in group L than in group N. The incidence of lung complications in group L (18 cases, 60 %) was lower than that in group N (26 cases, 86.7 %, χ2 = 5.46, P = 0.02); comparing LUS between T0 and T3, LUS decreased in a greater number of cases in group L (15, 50 %) than in group N (7 cases, 23.3 %, χ2 = 4.59, P = 0.032). ConclusionLung ultrasonography can effectively help assess lung conditions. Optimization guided by lung ultrasound in ultrafast track anesthesia can significantly reduce postoperative lung complications.

Association of clonal haematopoiesis with severe postoperative complications in patients undergoing radical oesophagectomy

BackgroundClonal haematopoiesis (CH) is an age-associated clonal expansion of blood cells driven by leukaemia-associated somatic mutations. Although CH has been reported to be a risk factor for leukaemia and a number of non-haematopoietic diseases, its role in perioperative medicine remains unexplored. MethodsThis was a single-centre, prospective, observational study. Patients undergoing radical oesophagectomy were enrolled, and peripheral blood samples were collected for DNA sequencing. Patients with haematopoietic somatic mutations (variant allele frequencies ≥1%) in the DNMT3A gene, TET2 gene, or both were defined as CH carriers. The primary outcome was the incidence of severe postoperative complications (Clavien–Dindo classification ≥3). The secondary outcomes included the major types of postoperative complications, mortality, and other common perioperative variables. ResultsClonal haematopoiesis was found in 21.2% (33/156) of the patients (mean age: 66 yr [range: 26–79 yr]; 83% males). Some 14/33 (42.4%) patients with CH had severe postoperative complications, compared with patients without CH carriers (28/123 [22.8%]; P=0.024). Multivariable logistic regression analysis showed that CH was associated with an increased risk of developing severe postoperative complications (odds ratio, 3.63; 95% confidence interval, 1.37–9.66; P=0.010). Among the major postoperative complications, the incidence of pulmonary complications was significantly higher in the patients with CH than in those without CH (15 in 33 [45.5%] vs 30 in 123 [24.4%], P=0.018). ConclusionsClonal haematopoiesis was associated with a higher incidence of severe postoperative complications in patients undergoing radical oesophagectomy, suggesting that clonal haematopoiesis can play an important role in perioperative medicine.

No difference in the incidence of postoperative pulmonary complications between abdominal laparoscopy and laparotomy for minimally invasive thoracoscopic esophagectomy: a retrospective cohort study using a nationwide Japanese database.

There remains a lack of evidence regarding the optimal abdominal approach, including laparoscopy, hand-assisted, and open laparotomy for minimally invasive thoracoscopic esophagectomy. We aimed to compare the incidence of postoperative complications, particularly pulmonary complications, between laparoscopy and open laparotomy for minimally invasive thoracoscopic esophagectomy using nationwide Japanese databases. Data from patients in the National Clinical Database (NCD) who underwent thoracoscopic esophagectomy for esophageal cancer were analyzed. The incidence of pulmonary complications was compared between abdominal laparoscopy and laparotomy after matching the propensity scores (PS) from preoperative factors to account for confounding bias. Laparoscopic-assisted surgery (LAS) was also compared to hand-assisted laparoscopic surgery (HALS). Of the 24,790 patients who underwent esophagectomy between 2018 and 2021, data from 12,633 underwent thoracoscopic procedure. The proportion of patients who experienced pulmonary complications did not significantly differ between the laparoscopy group and the laparotomy group after matching (664/3195 patients, 20.8% versus 702/3195 patients, 22.0%; P = 0.25). No difference in the incidence of pulmonary complications was observed among patients treated using the laparoscopic approach (508/2439 patients, 20.8% in the LAS group versus 498/2439 patients, 20.4% in the HALS group; P = 0.72). We observed no significant difference in the incidence of postoperative pulmonary complications between laparoscopy and laparotomy for thoracoscopic esophagectomy. Short-term outcomes were similar between the laparoscopic-assisted approach and the hand-assisted approach. This study provides valuable insights into the optimal abdominal approach for thoracoscopic esophagectomy using data from a nationwide database that reflect real-world clinical practice.

Assessment of safety during hospitalization for patients undergoing Surgery after neoadjuvant therapy for moderately advanced Esophageal cancer

PurposeTo study the safety of patients with moderately advanced esophageal cancer during their hospital stay after undergoing surgery.MethodsThe clinical and pathological data of 66 patients with locally advanced esophageal cancer discharged from the Department of Thoracic Surgery of Jiangsu University Hospital from January 2017 to October 2022 were selected, of whom 32 underwent direct surgery (control group) and 34 underwent neoadjuvant therapy followed by surgery (experimental group), to retrospectively analyze whether there were differences in surgical outcomes, complication rates, biochemical and infection indicators between the two groups.ResultsThe number of lymph node dissections, lymph node dissection rate, and hemoglobin value on the first day after the operation in the experimental group were smaller than those in the control group, and the difference was statistically significant (P < 0.05). The thoracic drainage volume of the experimental group was more than that of the control group, and the difference was statistically significant (P < 0.05). The incidence of pulmonary complications in the experimental group was higher than that in the control group, especially pulmonary infection, and the difference was statistically significant (P < 0.05). Compared with the control group, the experimental group was more prone to anastomotic leakage, and the difference was statistically significant (P < 0.05).ConclusionNeoadjuvant therapy combined with surgery for patients with advanced esophageal cancer is generally safe during hospitalization.

Effect of driving pressure-guided positive end-expiratory pressure on postoperative pulmonary complications in patients undergoing laparoscopic or robotic surgery: a randomised controlled trial

BackgroundIndividualised positive end-expiratory pressure (PEEP) improves respiratory mechanics. However, whether PEEP reduces postoperative pulmonary complications (PPCs) remains unclear. We investigated whether driving pressure-guided PEEP reduces PPCs after laparoscopic/robotic abdominal surgery. MethodsThis single-centre, randomised controlled trial enrolled patients at risk for PPCs undergoing laparoscopic or robotic lower abdominal surgery. The individualised group received driving pressure-guided PEEP, whereas the comparator group received 5 cm H2O fixed PEEP during surgery. Both groups received a tidal volume of 8 ml kg−1 ideal body weight. The primary outcome analysed per protocol was a composite of pulmonary complications (defined by pre-specified clinical and radiological criteria) within 7 postoperative days after surgery. ResultsSome 384 patients (median age: 67 yr [inter-quartile range: 61–73]; 66 [18%] female) were randomised. Mean (standard deviation) PEEP in patients randomised to individualised PEEP (n=178) was 13.6 cm H2O (2.1). Individualised PEEP resulted in lower mean driving pressures (14.7 cm H2O [2.6]), compared with 185 patients randomised to standard PEEP (18.4 cm H2O [3.2]; mean difference: -3.7 cm H2O [95% confidence interval (CI): -4.3 to -3.1 cm H2O]; P<0.001). There was no difference in the incidence of pulmonary complications between individualised (25/178 [14.0%]) vs standard PEEP (36/185 [19.5%]; risk ratio [95% CI], 0.72 [0.45–1.15]; P=0.215). Pulmonary complications as a result of desaturation were less frequent in patients randomised to individualised PEEP (8/178 [4.5%], compared with standard PEEP (30/185 [16.2%], risk ratio [95% CI], 0.28 [0.13–0.59]; P=0.001). ConclusionsDriving pressure-guided PEEP did not decrease the incidence of pulmonary complications within 7 days of laparoscopic or robotic lower abdominal surgery, although uncertainty remains given the lower than anticipated event rate for the primary outcome.

280. FEASIBILITY OF ROBOTIC-ASSISTED SURGERY FOR BENIGN ESOPHAGEAL LESIONS: SINGLE-CENTER EXPERIENCE

Abstract Background Benign esophageal lesions are uncommon conditions compared to malignant cases. Thoracotomy is an extremely invasive procedure that can cause severe complications and delay recovery. Conventional VATS is limited in its approach to deep and narrow angles and difficult to manipulate due to abundance of vital structures that are always mobile in mediastinal area. Robotic-assisted surgery is a new challenge that aims to achieve minimally invasive procedures and improve postoperative outcomes for benign esophageal lesions. Methods We conducted a retrospective analysis of a single-center database from May 2012 to November 2022, including patients aged 20–75 years with diagnosed benign esophageal lesions such as esophageal leiomyoma and esophageal diverticulum who underwent robotic-assisted esophageal surgery using the Da Vinci Robotic surgery system. The operation was performed using either a transthoracic or transabdominal approach. Patient data, surgical procedures, interventions, and early outcomes (within 30 days post-operation) were collected and analyzed to assess postoperative variables. The study included 13 patients, and the primary outcome was the incidence of pulmonary complications during the hospital stay. Results The number of patients with each esophageal lesion was as follows: esophageal leiomyoma, 6 cases (46.1%); esophageal diverticulum, 3 cases (23.1%); and other benign lesions, 4 cases (30.8%). Robotics approaches were divided into 11 cases (84.6%) and 2 cases (15.4%) for transthoracic and transabdominal, respectively. The overall incidence of postoperative pulmonary complications was 5 cases (38.5%), with mild pulmonary infection occurred in 2 cases (15.4%). Other pulmonary complications occurred in the transthoracic approach due to patient characteristics related to underlying lung diseases, such as COPD and asthma. There was no evidence of 30 days mortality in our series. Conclusion Robotic-assisted surgery is feasible for benign esophageal surgery using both transthoracic and transabdominal approaches. Robotic devices can provide stabilization for both 3D camera views and instrument arms, particularly enhancing suturing ability. Robotic surgery is precise and maneuverable, with potential to perform intricate surgical procedures in tight angles and confined spaces such as the thoracic cavity and hiatal area. These factors can improve the overall operative outcome and enhance recovery due to minimally invasive access.

274. ROBOTIC-ASSISTED THORACOSCOPIC ESOPHAGECTOMY WITH MEDIASTINAL LYMPH NODE DISSECTION: DOES IT FEASIBLE FOR ESOPHAGEAL SQUAMOUS CELL CARCINOMA SURGERY?

Abstract Background Esophageal cancer is sixth leading cause of cancer-related mortality globally in 2020. Esophageal squamous cell carcinoma is one of most aggressive and need extensive operative treatment for radical and oncologic purpose. Conventional thoracotomy is highly invasive, conventional video-assisted is quite technical difficulty related with deep and narrow angle of exposure. Robotic-assisted procedure is new challenging to beat this limitation. This is descriptive report of initial robotic-assisted experiences regard to feasibility, safety and oncologic outcome. Methods We conducted a retrospective analysis of a single-center database from March 2012 to February 2023, including patients aged 45–85 years with resectable lesions of the esophageal squamous cell carcinoma who underwent robotic-assisted thoracoscopic esophagectomy using the Da Vinci Robotic surgery system. Patient data, surgical procedures, interventions, and early outcomes (within 30 days postoperation) were collected and analyzed to assess postoperative variables and adequacy of cancer clearance. The study included 12 patients, and the primary outcome was the incidence of pulmonary complications during the hospital stay. Results The overall incidence of postoperative pulmonary complications was 4cases (33.3%), with mild pulmonary infection occurring in 2cases (16.7%) without 30-day mortality in robotic-assisted thoracoscopic esophagectomy. The median admission period were 2 days and 15 days for ICU and hospital stay, respectively. The median time for the thoracic phase of operation was 210 minutes (150-445 minutes), and the median blood loss volume was 55 mL (20–300 mL). Pathological results showed that overall proximal and distal margins were uninvolved by tumor, and the median number of lymph nodes retrieval in the thoracic region was 22.5lymph nodes (14-73lymph nodes). 41.7% of patients were classified in pathological stage I. Conclusion Robotic-assisted thoracoscopic esophagectomy has shown promising early postoperative outcomes, low blood loss volume, short ICU and hospital stay, a low rate of pulmonary complications and including adequate lymph node retrieval and pathological results. These findings support the feasibility and safety of robotic-assisted thoracoscopic esophagectomy, which enhance postoperative recovery and improve surgical outcomes for the treatment of esophageal squamous cell carcinoma.

148. COMPARISON OF EARLY POSTOPERATIVE OUTCOME BETWEEN OPEN AND MINIMALLY INVASIVE TRANSTHORACIC ESOPHAGECTOMY FOR ESOPHAGEAL CANCER: A RETROSPECTIVE STUDY

Abstract Background Esophagectomy is a highly invasive surgical procedure for esophageal cancer, with open thoracotomy associated with a significant risk of pulmonary complications. Minimally invasive techniques, such as minimally invasive esophagectomy (MIE), are expected to reduce these complications and enhance postoperative recovery. This study aimed to compare the early postoperative outcomes of patients who underwent open esophagectomy versus MIE. Methods We conducted a retrospective study using a single-center database from January 1, 2010, to February 28, 2023, including patients aged 18–90 years with a resectable lesion of the esophagus or esophagogastric junction who underwent either open transthoracic esophagectomy or MIE (thoracoscopic/robotic-assisted). Patient data, surgical procedures, interventions, and early outcomes (within 30 days of operation) were collected and analyzed. The study included a total of 76 patients, with 50 patients in open esophagectomy group and 26 patients in MIE group. The primary outcome was the incidence of pulmonary complications during the hospital stay, and logistic regression was used for data analysis. Results The overall incidence of pulmonary complications was 37 cases (74%) in the open esophagectomy group and 14 cases (53.8%) in the MIE group, with the incidence of pulmonary infection occurring in 19 cases (38%) and 8 cases (30.8%), respectively. Perioperative mortality was 1 cases (2%) in the open esophagectomy group and 0 cases (0%) in the MIE group. After adjusting for age, sex, BMI, smoking, COPD, and operative time, the open esophagectomy group had a 4.29 times higher risk of pulmonary complications than the MIE group (odds ratio 4.29, 95% confidence interval 1.30–14.16; p = 0.017). Conclusion Our study demonstrates that MIE is associated with a lower incidence of pulmonary complications, reduced blood loss, and shorter ICU stays compared to open esophagectomy. Rates of anastomosis leakage, vocal cord paralysis, and hospital stays were comparable. These findings support the feasibility and safety of MIE, potentially improving surgical outcomes and enhancing postoperative recovery for the treatment of esophageal cancer.

Effects of Press Needling combined with general anesthesia on postoperative analgesia in thoracoscopic pulmonary resection for lung cancer: A randomized, single-blind, controlled trial

ObjectivesTo investigate the effects of press needle therapy on postoperative analgesia and other relevant complications in patients undergoing thoracoscopic pulmonary resection. Designrandomized, single-blind, controlled trial SettingTeaching hospitals affiliated with universities. InterventionsEighty-six patients were randomized into: the Acu group (press-needle group) and the control group Main outcome measuresPain levels 24, 48, and three months after surgery were measured using the numeric rating scale (NRS). Perioperative hemodynamics, total and effective pressing numbers of patient-controlled intravenous analgesia (PCIA), and incidence of postoperative pulmonary complications were recorded. Peripheral blood samples were collected to measure the levels of inflammatory mediators ResultsAcu group had significantly lower NRS scores at 24 and 48 h after operation (NRS scores on movement at 24 h after surgery: Acu vs. Control, 3 (2,3) vs. 3 (3,5), Z = −3.393, P < 0.01 and NRS scores on movement at 48 h after surgery: 2 (1,3) vs. 3 (2,5), Z = −3.641, P < 0.01), lower number of PCIA attempts and effective rates (mean total pressing numbers: 4(2,8) vs. 6(3,19), Z = −1.994, P = 0.046 and mean effective pressing numbers: 3(2,8) vs. 6(3,16), Z = −2.116, P = 0.034). The Acu group had significantly reduced IL-1 (14.52 ± 3.84 vs. 16.36 ± 3.30, mean difference (MD): − 1.85, 95% confidence interval (CI): − 3.46, − 0.23, P = 0.026), HIF-1α (10.15 ± 1.71 vs. 10.96 ± 1.73, MD: −0.81, 95% CI: −1.59, −0.04, P = 0.040) and the incidence of pulmonary complications after surgery. ConclusionPress needles are a non-invasive and feasible adjunctive intervention for postoperative analgesic management in patients undergoing thoracoscopic pulmonary resection.

Non-Gastrointestinal Complications and Short-Term Outcomes in Patients With Anastomotic Leak After Colon Resection: A Propensity Matched Analysis of American College of Surgeons National Surgical Quality Improvement Program Database

Introduction: Anastomotic leak is a devastating complication after colorectal surgery. There is paucity of data on non-gastrointestinal complications after anastomotic leak in this population. We aimed to investigate non-gastrointestinal complications, as well as causes of major morbidity and mortality following anastomotic leak after colorectal resection and hypothesized that non-gastrointestinal complications after anastomotic leak are a sizable proportion of the overall morbidity and mortality in this population. Methods: We used the ACS NSQIP database, and searched for CPT codes for colorectal procedures with primary anastomosis between 2015-2019. The cohorts (anastomotic leak vs. no-leak) were aligned using propensity score matching, and 30-day mortality, length of stay, and readmission outcomes were compared. Results: We identified 4881 patients with anastomotic leak and 150331 patients with no-leak. The overall leak rate was 3.14%. Anastomotic leak group had an 85% longer length-of-stay. Predicted mean (95% CI) length-of-stay for the leak group was 10.2 (9.9-10.5) days vs. 5.5 (5.4-5.7) days for the no-leak group. Anastomotic leak was associated with a higher 30-day risk of unplanned return to the operating room (OR 34.5; 95% CI 27.2-43.8), and thirty-day mortality (OR 2.8; 95% 2.2-3.5). Anastomotic leak was associated with a higher incidence of pulmonary complications including: pneumonia (OR 4.4; 95% CI 3.5-5.6), unplanned intubation (OR 6.3; 95% CI 4.8-8.3), mechanical ventilation (OR 6.3; 95% CI 5.1-8.0), and pulmonary embolism (OR 4.3; 95% CI 2.6-7.0); cardiac complications, including myocardial infarction (OR 2.9 (95% CI 2.0-4.2) and cardiac arrest (OR 3.2; 95% CI 2.1-4.9); and new-onset renal failure requiring dialysis (OR 3.8; 95% CI 2.6-5.5). There was no significant difference in risk of acute kidney injury (OR 1.1; 95% CI 0.6-2.0), and stroke (OR 1.8; 95% CI 0.9-3.6). Conclusion: Colorectal anastomotic leak independently lengthens length-of-stay, and is associated with increased mortality (2.7% vs. 7.2%) after colorectal surgery with an enteric anastomosis.

Prehabilitation bundle can reduce incidence of postoperative pulmonary complications.

Elective major colorectal surgery is still associated with postoperative morbidity and mortality. Preoperative optimization can potentially reduce postoperative pulmonary complications, which significantly prolong recovery and increase the risk of mortality. The aim of this study was to evaluate the effect of the prehabilitation bundle on postoperative pulmonary complications. All patients undergoing elective colorectal procedure for benign or malignant diagnosis before and after the introduction of the prehabilitation bundle were enrolled in the study. Prehabilitation was focused on nutritional support, regular aerobic and muscle strength exercise, preoperative optimization of anaemia, improvement of oral hygiene including regular chlorhexidine mouth wash, psychological support, restriction of smoking and alcohol consumption. In addition to the general characteristics, compliance with individual measures, incidence of pulmonary complications and length of stay were monitored. A total of 596 patients were included in the study (226 before and 370 after the implementation of the package). After the introduction of prehabilitation, the incidence of postoperative pulmonary complications decreased significantly - 29 (13%) vs. 17 (4.6%), RR: 0.21-0.67), p=0.001 and shorter length of stay was observed à 9.7 (±8.8) to 7.7 (±5.5) days (p=0.0005). Except for optimization of anaemia, compliance with the individual components of the established bundle was very good. Introduction of a prehabilitation bundle focused on improvement of cardiorespiratory capacity, optimization of diet and oral hygiene, can reduce the risk of postoperative pulmonary complications and shorten the length of stay.

Effects of high flow nasal cannula following minimally invasive esophagectomy in ICU patients: A prospective pre-post study

Patients with esophageal cancer who undergo minimally invasive esophagectomy are at risk of postoperative pulmonary complications. High-flow nasal cannula oxygen therapy delivers humidified, warmed positive airway pressure but has not been applied routinely after surgery. Here, we aimed to compare high-flow nasal cannula and conventional oxygen therapy in patients with esophageal cancer during intensive care unit hospitalization 48h postoperatively. In this prospective pre- and post-intervention study, patients with esophageal cancer who underwent elective minimally invasive esophagectomy (MIE) and were extubated in the operation room and admitted to the intensive care unit postoperatively were assigned to receive either high-flow nasal cannula (HFNCO) or standard oxygen (SO) therapy. Participants in the SO group were recruited before January 2020, and those in the HFNCO group were enrolled after January 2020. The primary outcome was the difference in postoperative pulmonary complication incidence. Secondary outcomes were the occurrence of desaturation within 48h, PaO2/FiO2 within 48h, anastomotic leakage, length of intensive care unit and hospital stay, and mortality. The standard oxygen and high-flow nasal cannula oxygen groups comprised 33 and 36 patients, respectively. Baseline characteristics were comparable between groups. In the HFNCO group, postoperative pulmonary complication incidence was significantly reduced (22.2% vs 45.5%) and PaO2/FiO2 was significantly increased. No other between-group differences were observed. HFNCO therapy significantly reduced postoperative pulmonary complication incidence after elective MIE in patients with esophageal cancer without increasing the risk of anastomotic leakage.

Non-Intubated Video-Assisted Thoracoscopic Surgery.

Double-lumen intubation under general anesthesia is currently the most commonly performed intubation technique for pneumonectomy, wedge resection of the lung, and lobectomy. However, there is a high incidence of pulmonary complications arising from general anesthesia with tracheal intubation. Non-intubation with the preservation of voluntary breathing is an alternative to anesthesia. Non-intubation procedures minimize the adverse effects of tracheal intubation and general anesthesia, such as intubation-related airway trauma, ventilation-induced lung injury, residual neuromuscular blockade, and post-operative nausea and vomiting. However, the steps for non-intubation procedures are not detailed in many studies. Here, we present a concise non-intubated protocol for the performance of video-assisted thoracoscopic surgery with preserved autonomic breathing. This article identifies the conditions necessary to convert from non-intubated to intubated anesthesia and also discusses the advantages and limitations of non-intubated anesthesia. In this work, this intervention was performed on 58 patients. In addition, the results of a retrospective study are presented. Compared with intubated general anesthesia, patients in the non-intubated video-assisted thoracic surgery group had lower rates of post-operative pulmonary complications, shorter operative times, less intraoperative blood loss, shorter PACU stays, a lower number of days to chest drain removal, less post-operative drainage, and shorter hospital stays.

Postoperative awake prone position in geriatric patients with hip fractures: a protocol for a randomized controlled trial on the efficacy of postoperative prone position in reducing pulmonary complications and improving oxygenation

IntroductionPostoperative pulmonary complications (PPCs) are prevalent in geriatric patients with hip fractures. Low oxygen level is one of the most important risk factors for PPCs. Prone position has been proven efficacy in improving oxygenation and delaying the progress of pulmonary diseases, especially in patients with acute respiratory distress syndrome induced by multiple etiologies. The application of awake prone position (APP) has also attracted widespread attention in recent years. A randomized controlled trial (RCT) will be carried out to measure the effect of postoperative APP in a population of geriatric patients undergoing hip fracture surgery.MethodsThis is an RCT. Patients older than 65 years old admitted through the emergency department and diagnosed with an intertrochanteric or femoral neck fracture will be eligible for enrollment and assigned randomly to the control group with routine postoperative management of orthopedics or APP group with an additional prone position for the first three consecutive postoperative days (PODs). Patients receiving conservative treatment will not be eligible for enrollment. We will record the difference in the patient’s room-air-breathing arterial partial pressure of oxygen (PaO2) values between the 4th POD (POD 4) and emergency visits, the morbidity of PPCs and other postoperative complications, and length of stay. The incidence of PPCs, readmission rates, and mortality rates will be followed up for 90 PODs.DiscussionWe describe the protocol for a single-center RCT that will evaluate the efficacy of postoperative APP treatment in reducing pulmonary complications and improving oxygenation in geriatric patients with hip fractures.Ethics and disseminationThis protocol was approved by the independent ethics committee (IEC) for Clinical Research of Zhongda Hospital, Affiliated to Southeast University, and is registered on the Chinese Clinical Trial Registry. The findings of the trial will be disseminated through peer-reviewed journals.Ethics approval number2021ZDSYLL203-P01Trial registrationChiCTR ChiCTR2100049311.
