Time to surgical stabilization of rib fractures: does it impact outcomes?

Objectives: Rib fractures are common, morbid, and potentially lethal. Intuitively, if interventions to mitigate downstream effects of rib fractures can be implemented early, likelihood of developing these complications should be reduced. Surgical stabilization of rib fractures (SSRF) is one therapeutic intervention shown to be useful for mitigating complications of these common fractures. Our aim was to investigate for association between time to SSRF and complications among patients with isolated rib fractures undergoing SSRF. Methods: The 2016-2019 American College of Surgeons Trauma Quality Improvement Program (TQIP) database was queried to identify patient >18 years with isolated thoracic injury undergoing SSRF. Patients were divided into three groups: SSRF ≤2 days, SSRF >2 days but <3 days, and SSRF >3 days. Poisson regression, and adjusting for demographic and clinical covariates, was used to evaluate the association between time to SSRF and the primary endpoint, in-hospital complications. Quantile regression was used to evaluate the effects of time to SSRF on the secondary endpoints, hospital and intensive care unit (ICU) length of stay (LOS). Results: Out of 2185 patients, 918 (42%) underwent SSRF <2 days, 432 (20%) underwent SSRF >2 days but <3 days, and 835 (38%) underwent SSRF >3 days. Hemothorax was more common among patients undergoing SSRF >3 days, otherwise all demographic and clinical variables were similar between groups. After adjusting for potential confounding, SSRF >3 days was associated with a threefold risk of composite in-hospital complications (adjusted incidence rate ratio: 3.15, 95% CI 1.76 to 5.62; p<0.001), a 4-day increase in total hospital LOS (change in median LOS: 4.09; 95% CI 3.69 to 4.49, p<0.001), and a nearly 2-day increase in median ICU LOS (change in median LOS: 1.70; 95% CI 1.32 to 2.08, p<0.001), compared with SSRF ≤2 days. Conclusion: Among patients undergoing SSRF in TQIP, earlier SSRF is associated with less in-hospital complications and shorter hospital stays. Standardization of time to SSRF as a trauma quality metric should be considered. Level of evidence: Level II, retrospective.

Delayed hemothorax following blunt thoracic trauma: a case report.

BACKGROUND: Late hemothorax is a rare complication of blunt chest trauma. The longest reported time interval between the traumatic event and the development of hemothorax is 44 days. CASE PRESENTATION: An elderly patient with right-sided rib fractures from chest trauma, managed initially with closed thoracostomy, presented with a delayed hemothorax that occurred 60 days after initial management, necessitating conservative and then surgical intervention due to the patient's frail condition and associated complications. CONCLUSIONS: This case emphasizes the clinical challenge and significance of delayed hemothorax in chest trauma, highlighting the need for vigilance and potential surgical correction in complex presentations, especially in the elderly.

Minimally invasive management of thoracic trauma: current evidence and guidelines.

Minimally invasive procedures are being increasingly proposed for trauma. Injuries to the chest wall and/or lung have historically been managed by drainage with a large bore thoracostomy tube, while cardiac injuries have mandated sternotomy. These treatments are associated with significant patient discomfort. Percutaneous placement of small 'pigtail' catheters was initially designed for drainage of simple pericardial fluid. Their use subsequently expanded to drainage of the pleural cavity. The role of pigtail catheters for primary treatment of traumatic pneumothorax and hemopneumothorax has increased, while their use for pericardial fluid after trauma remains controversial. Pericardial windows have alternatively been purposed as a minimally invasive treatment option for possible hemopericardium. The aim of this article is to review the current evidence and guidelines for minimally invasive management of chest trauma.

Comparison between use of a pleural drainage system with flutter valve and a conventional water-seal drainage system after lung resection: a randomized prospective study

ABSTRACT BACKGROUND: There is still a debate regarding the most appropriate pleural collector model to ensure a short hospital stay and minimum complications. OBJECTIVES: To study aimed to compare the time of air leak, time to drain removal, and length of hospital stay between a standard water-seal drainage system and a pleural collector system with a unidirectional flutter valve and rigid chamber. DESIGN AND SETTING: A randomized prospective clinical trial was conducted at a high-complexity hospital in São Paulo, Brazil. METHODS: Sixty-three patients who underwent open or video-assisted thoracoscopic lung wedge resection or lobectomy were randomized into two groups, according to the drainage system used: the control group (WS), which used a conventional water-seal pleural collector, and the study group (V), which used a flutter valve device (Sinapi® Model XL1000®). Variables related to the drainage system, time of air leak, time to drain removal, and time spent in hospital were compared between the groups. RESULTS: Most patients (63%) had lung cancer. No differences were observed between the groups in the time of air leak or time spent hospitalized. The time to drain removal was slightly shorter in the V group; however, the difference was not statistically significant. Seven patients presented with surgery-related complications: five and two in the WS and V groups, respectively. CONCLUSIONS: Air leak, time to drain removal, and time spent in the hospital were similar between the groups. The system used in the V group resulted in no adverse events and was safe.

Implementation of a novel thoracostomy tube trainer with real-time feedback.

Objectives: Simulation-based training leads to improved clinical performance but may be influenced by quality and frequency of training. Within simulation training, chest tube insertion remains a challenge as one of the main pitfalls of insertion is a controlled pleural entry. This study evaluates the efficacy of a novel training model with real-time pressure monitoring, the average force to pleural entry in a model and the utility of audio and visual feedback. Methods: This proprietary training model comprised a modified Kelly clamp device with three force sensors at the index finger (sensor 1) and two finger loops (sensors 2 and 3), and a manikin with a replaceable chest wall pad. Standard force values (Newtons (N)) were obtained by experts; expert data revealed that 3-5 s was an acceptable time range to complete the chest tube insertion. Participant level ranged from Post-graduate Year (PGY)-1 to PGY-6 with 13 total participants. Each individual was provided an introduction to the procedure and chest tube trainer. Force (N) and time (ms) measurements were obtained from entry through dermis to pleural space puncture. A significant pressure drop suggested puncturing through the chest wall (completion of the procedure). Results: Force data were captured during each phase of the procedure-linear, plateau, and drop. Linear phase (~3000 ms) was from start of procedure to point of maximum force (<30 N). Plateau phase was from maximum force to just before a drop in pressure. Drop phase was a drop in pressure by 5+ N in a span of 150 ms signaling completion of procedure. All participants were able to complete the task successfully. Force for pleural entry ranged from 17 N to 30 N; time to pleural entry ranged from 7500 to 15 000 ms. There was variability in use of all three sensors. All participants used the index sensor, however there was variability in the use of the loop sensors depending on the handedness of the participant. Left-handed users relied more on sensors 1 and 3 while right-handed users relied more on sensors 1 and 2. Given this variability, only force measurements from sensor 1 were used for assessment. Conclusions: This novel force-sensing chest tube trainer with continuous pressuring monitoring has a wide range of applications in simulation-based training of emergency surgical tasks. Next steps include evaluating its impact on accuracy and efficiency. Applications of real-time feedback measuring force are broad, including vascular access, trocar placement and other common procedures. Level of evidence: Level IV, prospective study.

The Use of Fissios App© as a Complement to a Face-to-Face Respiratory Physiotherapy Program versus an Attendance-Only Face-to-Face Physiotherapy Program in Patients Scheduled for Thoracic Surgical Procedures Reduces the Risk of Developing Postoperative Pulmonary Complications-A Quasi-Experimental Study.

Postoperative pulmonary complications (PPCs) increase the hospital length of stay (LOS) and the cost of healthcare associated with surgical procedures. Strategies to reduce PPCs begin before surgery and continue in the postoperative period. Fissios App© is a smartphone application that contains perioperative medical advice and a structured respiratory physiotherapy program. The objective was to implement the use of this app in a group of patients scheduled for a thoracic surgical procedure and determine its efficacy in reducing PPCs. This was a quasi-experimental study in which all patients attended a face-to-face respiratory physiotherapy program, and the intervention group used Fissios App© as a complement. We prospectively recorded the postoperative evolution of both groups, analyzed the categorical differences and quantitative variables, and created a binary logistic regression model. We recruited 393 patients (131 intervention and 262 control). The intervention group had a lower incidence of PPCs (12.2% versus 24% in the control group, p = 0.006), a shorter LOS (a median of 3 days (IQR = 2-5) versus 4 days (IQR = 3-6, p = 0.001) in the control group), and a reduction in the risk of developing PPCs by 63.5% (OR: 0.365, 95% CI: 0.17-0.78). The use of Fissios App© improved the clinical outcomes after surgery and reduced the probability of developing PPCs.

Brief report on the development of hemorrhagic pericardial effusion after thoracic surgery for traumatic injuries.

Introduction: Hemorrhagic pericardial effusion (HPE) is a rare but life-threatening diagnosis that may occur after thoracic trauma. Previous reports have concentrated on delayed HPE in those who did not require initial surgical intervention for their traumatic injuries. In this report, we identify and characterize the phenomenon of HPE after emergent thoracic surgery for trauma. Methods: This is a retrospective review of patients who required emergent thoracic surgery for trauma at a level 1 trauma center from 2017 to 2021. Using the institutional trauma database, demographics, injury characteristics, and outcomes were compared between patients with HPE and those without HPE after thoracic surgery for trauma. Results: Ninety-one patients were identified who underwent emergent thoracic surgery for trauma. Most were young men who sustained a penetrating thoracic injury. Seven patients (7.7%) went on to develop HPE. Patients who developed HPE were younger (18 vs. 32 years, p=0.034), required bilateral anterolateral thoracotomy (85% vs. 7%, p<0.001), and were more likely to have pulmonary injuries (100% vs. 52.4%, p<0.001). Five patients with HPE survived to hospital discharge. The two patients with HPE who died were both coagulopathic and had HPE diagnosed within 4 days of injury. The median time to HPE diagnosis in survivors was 24 days with four of five HPE survivors on therapeutic anticoagulation at the time of diagnosis. Conclusions: HPE may occur after emergent thoracic surgery for trauma. Those at highest risk of HPE include younger patients with bilateral thoracotomy incisions and pulmonary injuries. Early HPE, clinical signs of tamponade, and/or coagulopathy in patients with HPE portend a worse prognosis. Surgeons and trauma team members caring for patients after emergent thoracic exploration for trauma should be aware of this potentially devastating complication and should consider postoperative echocardiography in high-risk patients.

Patterns of Postoperative Changes in Lung Volume and Perfusion Assessed by Dual-Energy CT: Comparison of Lobectomy and Limited Resection.

BACKGROUND. Pulmonary function tests (PFTs) and perfusion scintigraphy have limited utility for evaluating postoperative changes in regional pulmonary function after lung cancer resection surgery. OBJECTIVE. The purpose of this study is to compare postoperative changes in lung volume and perfusion, as assessed by dual-energy CT (DECT), between patients undergoing surgical resection of lung cancer by lobectomy versus limited resection as well as to assess associations between such changes and the lobar location of the resected tumor. METHODS. This study entailed a retrospective post hoc analysis of a prospective study that enrolled patients awaiting lung cancer resection surgery between March 2019 and February 2020. Eighty-one patients (38 men and 43 women; mean age, 60.5 ± 8.9 [SD] years), 43 of whom underwent lobectomy and 38 of whom underwent limited resection, were included. Patients underwent thoracic DECT and PFT evaluation preoperatively and at 6 months postoperatively. Pulmonary lobes were segmented. Lobar lung volume and lung perfusion ratios (both relative to whole-lung values) were computed. Perfusion measures reflected DECT-derived iodine content. Patients completed 6-month postoperative quality-of-life (QOL) questionnaires. RESULTS. Patients undergoing lobectomy, compared with those undergoing limited resection, had greater increases in the lung volume ratio of the ipsilateral nonresected lobe(s) (mean, 42.3% ± 24.2% [SD] vs 22.9% ± 13.2%, p < .001) and the contralateral lung (mean, 14.6% ± 14.0% vs 6.4% ± 6.9%, p = .002) as well as greater increases in the lung perfusion ratio of the ipsilateral nonresected lobe(s) (mean, 39.9% ± 20.7% [SD] vs 22.8% ± 17.8%, p < .001) and the contralateral lung (mean, 20.9% ± 9.4% vs 4.3% ± 5.6%, p < .001). In patients with right lower lobe tumors, the largest postoperative increases in the lung volume ratio were in the right middle lobe in those undergoing lobectomy (mean, 44.1% ± 21.0%) and limited resection (mean, 24.6% ± 14.5%), whereas the largest postoperative increase in the lung perfusion ratio was in the left lower lobe in those undergoing lobectomy (mean, 53.9% ± 8.6%) and in the right middle lobe in those undergoing limited resection (mean, 32.5% ± 24.1%). Otherwise, the largest increases in lung volume and perfusion ratios occurred in the ipsilateral nonresected lobes (vs the contra-lateral lobes), regardless of the operative approach used and the lobar location. Changes in the lung volume and perfusion ratios in the ipsilateral lobe(s) and the contralateral lung showed weak correlations with certain QOL scores (e.g., for role functioning: ρ = 0.234-0.279 [volume] and -0.233 to -0.284 [perfusion]). CONCLUSION. DECT depicts patterns of lung volume and perfusion changes after lung cancer surgery, depending on the surgical approach (lobectomy vs limited resection) used and the lobar location of the tumor. CLINICAL IMPACT. DECT-derived metrics can help understand variable physiologic impacts of lung cancer resection surgeries.

The practice of clinical pharmacists participating in the management of prophylactic antibiotics during the perioperative period of thoracic surgery / 中国基层医药

Objective:To explore the role of clinical pharmacists participating in the management of prophylactic antibiotics during the perioperative period of thoracic surgery, and to evaluate the effects after participating in the practice.Methods:The use of antimicrobials during the perioperative period of thoracic surgery in Wenjiang Hospital of Sichuan Provincial People's Hospital in August 2019 (pre-practice) was retrospectively analyzed. The existing problems were summarized, and the possible causes of the existing problems were analyzed. The improvement measures were jointly developed by clinical pharmacists and physicians. Clinical pharmacists continued to manage the use of antimicrobials by means of medication order reviews, ward rounds for pharmacy service, and medication training. The use of prophylactic antibiotics during the perioperative period of thoracic surgery was compared between August 2019 (pre-practice group) and December 2019 (post-practice group) and the practical effect was evaluated.Results:Clinical pharmacists reviewed perioperative patients' medication orders once a day, ward rounds for pharmacy service twice a week, and medication training once a month. Twenty-two patients were enrolled before practice, and 26 patients were enrolled after practice. There were no significant differences in age, sex, body weight, operative time, type of surgical incision, and preventive use of antibiotics between the two groups (all P > 0.05). In the post-practice group, the appropriate time for preoperative administration was 100.0%, which was significantly higher than 88.2% in the pre-practice group. The reasonable rate of preoperative preventive drug selection was 100.0%, which was significantly higher than 44.4% in the pre-practice group ( χ2 = 17.50, P < 0.001). In the post-practice group, the duration of preventive medication was (1.82 ± 0.59) days, which was significantly shorter than (7.54 ± 3.25) days in the pre-practice group ( t = 11.97, P < 0.001). In the post-practice group, the cost of antibacterial drugs was 316.00(237.00,454.25) yuan, which was significantly lower than 1 136.00(391.81 , 2 184.65) yuan in the pre-practice group ( Z = -2.78, P < 0.05). The defined daily dose of antibiotics among inpatients was 2.67(2.00,3.42), which was significantly lower than 8.88(3.92 , 19.18) in the pre-practice group ( Z = -3.26, P < 0.05). There were no significant differences in the incidence of postoperative pulmonary infection and total length of hospital stay between the two groups (both P > 0.05). Conclusion:Clinical pharmacists participating in the management practice of perioperative prophylactic antibiotics in thoracic surgery can effectively promote the rational application of perioperative antibiotics, markedly improve the reasonable rate of prophylactic drug delivery, shorten the course of prophylactic drugs, reduce the cost of antibiotics, decrease the defined daily dose of antibiotics, without increasing the risk of postoperative pulmonary infection and the total length of hospital stay.

Anaesthetic Management of Pulmonary Metastasectomy in a Patient Infected with Novel Corona Virus SARS-CoV-2.

Prioritisation of individual patients for thoracic surgeries gained importance during the current COVID-19 pandemic to ensure optimal utilisation of resources. We report a 76-year-old-male patient who presented to a tertiary care hospital in Muscat, Oman, 2020, with bilateral pulmonary metastasis. The patient underwent an urgent pulmonary metastasectomy with successful anaesthesia management in an elderly patient despite him testing positive for COVID-19 twice via real-time reverse transcription-polymerase chain reaction. At the 3-month follow-up some pulmonary abnormalities persisted but the patient was recovering well. This report discusses the rationale to perform surgery in this case and highlights the precautions taken for reducing aerosol generation during the various stages of anaesthesia.

Cáncer pulmonar: caracterización, estadificación y supervivencia en una cohorte de una década en un hospital del sistema público de salud de Chile / Lung cancer at a Chilean public hospital

Background: Lung cancer is the world's leading cause of cancer death. Aim: To describe the clinical, staging and survival characteristics of lung cancer in a public Chilean regional hospital. Material and Methods: Analysis of a prospective database of a thoracic surgery service, retrieving histologically confirmed lung cancer cases from January 2010 to December 2019 and reviewing their medical records. Cases were re-staged by the TNM-8 system and variables were compared between periods 2010-2014 and 2015-2019. Results: We retrieved 551 lung cancer cases, 333 (60 %) men, with a mean age of 65 years. Distant metastases were found in 72% of cases (excluding lymphatic metastases). Of the non-small cell lung cancers (NSCLC), 50 (10%) cases were in stage I, 18 (4%) in stage II, 81 (16%) in stage III and 347 (70%) in stage IV. Global five-year survival was 18%, 20% for NSCLC, 71% for excised NSCLC, 8% for non-excised NSCLC, 88% for stage I and 92% for subgroup IA. Resective surgery was performed in 81 (14%) cases. When comparing 2010-2014 and 2015-2019 periods, the frequency of resective surgery increased from 7% to 20%. Conclusions: The diagnosis of lung cancer was frequently made in advanced stages. There was a significant increase in early diagnosis and frequency of surgeries with curative intent in the second observation period.

Cardiac surgeons between apprehension and ethical duty in the COVID-19 pandemic.

BACKGROUND: Cardiothoracic surgeons are facing a big challenge in their surgical practice in the era of the COVID-19 pandemic. The attitude towards performing surgery is influenced by the pandemic. Setting special recommendations for safe cardiothoracic surgery is of extreme importance. METHODS: This was an observational cross-sectional survey that included 77 Egyptian cardiothoracic surgeons. The survey consisted of a self-administered constructed questionnaire with six sections, and was delivered as a Google Forms questionnaire (https://www.google.com/forms/about) that was sent to individuals via social networks and email. RESULTS: More than 80% of Egyptian cardiothoracic surgeons believe they and their patients are at risk. Out of all participants, none had actually been infected with COVID-19 but 26% had encountered a positive COVID-19 person in their surgical team. Although 51% were testing patients before surgery, they reported 9 confirmed cases postoperatively. Computed tomography was the most recommended investigation prior to surgery (by 69%). Most had postponed elective surgeries and only one-third of all surgeons recommended performing elective surgeries cautiously with pretesting for COVID-19 and maximizing protective measures, while more than 40% recommended not performing high-risk elective surgeries. CONCLUSION: We are committed to the safety of our patients, ourselves, our staff, and our families. Planning for the new phase of reopening, whether total reopening or step-by-step reopening, should carefully consider how we should utilize our resources, respect social distancing, and prevent exposure to untested patients or health workers who might turn out to be an undetected positive case.

Utility of thoracic computed tomography to predict need for early surgery and recurrence after first episode of primary spontaneous pneumothorax.

INTRODUCTION: CT imaging is not advocated by British Thoracic Society guidelines after first episode of primary spontaneous pneumothorax (PSP). There is emerging evidence that emphysema-like changes and CT-based dystrophy severity score (DSS) can predict need for early surgery and recurrence. OBJECTIVES: We aimed to assess the role of DSS during first episodes of PSP in predicting the need for early surgery and recurrence. METHODS: We conducted a retrospective analysis of consecutive PSP episodes (n=197) admitted to our institution from 1 January 2012 to 31 December 2017. DSS was calculated based on type, number and distribution of blebs and bullae. Patients were categorised as low-grade (0-3) or high-grade (4-6) DSS assessed by a thoracic radiologist. RESULTS: Forty-five PSP patients had CT at first presentation. Eight patients had low-grade DSS; all were managed non-surgically and none had recurrence over 12 months. Thirty-seven patients had high-grade DSS. Of these, 25 (67.5%) were managed surgically, with three having contralateral recurrence over 12 months; 12 (32.5%) were managed non-surgically, and of these two patients had ipsilateral recurrence over 12 months. CONCLUSION: DSS seems to predict the need for early surgery and recurrence and CT can be used to risk-stratify patients after a first episode of PSP.

Risk factors for postoperative nausea and vomiting in patients undergoing thoracic surgery / 中华麻醉学杂志

Objective:To identify the risk factors for postoperative nausea and vomiting (PONV) in the patients undergoing thoracic surgery.Methods:The medical records of patients of either sex, aged 18-80 yr, of American Society of Anesthesiologists physical status Ⅰ-Ⅲ, underwent elective thoracic surgery from January 2018 to January 2020, were collected retrospectively.The age, gender, educational background, American Society of Anesthesiologists physical status, motion sickness, history of smoking, history of drinking, history of heart disease, history of hypertension, history of diabetes, preoperative blood routine, liver function, parameters of electrolytes; operation method, type of operation, operation time, intraoperative nerve block, consumption of dexamethasone before anesthesia induction and intraoperative sufentanil and dexmedetomidine, use of postoperative patient-controlled intravenous analgesia (PCIA), and postoperative rescue opioid analgesics and antiemetics were recorded.The patients were divided into PONV group and non-PONV group depending on the occurrence of nausea and vomiting within 24 h after operation.PONV group was further divided into nausea group (PON group) and vomiting group (POV group) according to whether vomiting occurred.Logistic regression analysis was used to identify the risk factors for PONV.Results:A total of 3 791 patients were enrolled in this study, with 144 cases in PONV group and 3 647 cases in non-PONV group.The incidence of PONV was 3.80%.There were 38 patients in POV group, and the incidence was 26.4%.The results of logistic regression analysis showed that motion sickness, female, pulmonary wedge resection, postoperative PCIA and increased use of postoperative rescue opioid analgesics were risk factors for PONV in the patients undergoing thoracic surgery, intraoperative use of dexmedetomidine was a protective factor for PONV; motion sickness, female and history of hypertension were risk factors for postoperative vomiting in the patients at risk for PONV ( P<0.05). Conclusions:Motion sickness, female, pulmonary wedge resection, postoperative PCIA, and increased use of postoperative rescue opioid analgesics are risk factors and intraoperative use of dexmedetomidine is a protective factor for PONV in the patients undergoing thoracic surgery; motion sickness, female and history of hypertension are risk factors for postoperative vomiting in the patients at risk for PONV.

Effects of ultrasound-guided bilateral erector spinal plane nerve block on postoperative pain and sleep quality in children with pectus excavatum undergoing Nuss / 中国医师杂志

Objective:To investigate the effects of ultrasound-guided bilateral erector spinal plane nerve block on postoperative pain and sleep quality in children with pectus excavatum undergoing Nuss.Methods:From February 2020 to December 2021, 40 children with pectus excavatum undergoing Nuss from Hunan Children′s Hospital were prospectively selected and randomly divided into two groups: group E (group E) with erector spinal muscle plane block combined with general anesthesia and group G (group G) , with 20 patients in each group. After general anesthesia, ultrasound guided plane nerve block of bilateral erector spinal muscles was performed in group E, and general anesthesia with tracheal intubation was performed in group G. The Visual Analogue Scale (VAS) Score were recorded at 2, 6, 12, 24 and 48 hours after surgery; The addition of sufentanil, the time of extubation of post anesthesia recovery room (PACU) and the time of leaving the PACU in each group were recorded; The effective pressure times of analgesic pump and the number of people for remedial analgesia were recorded. Pittsburgh sleep quality index (PSQI) was used to score the sleep quality of children before and 2 days after surgery. The occurrence of hypoxemia and restlessness after extubation, nausea and vomiting, pneumothorax, local anesthetic poisoning and other complications were recorded.Results:The VAS score of group E at 2, 6, 12 and 24 hours after operation was lower than that of group G (all P<0.05). There was no significant difference in VAS score 48 hours after operation between the two groups ( P>0.05). The time of decannulation and recovery of PACU in group E was shorter than that in group G (all P<0.05). Compared with group G, there were fewer cases of sufentanil added in group E during operation, and the number of analgesia pump pressing times and cases of postoperative remedial analgesia in group E were less than those in group G (all P<0.05). The PSQI score of sleep quality index 2 days after operation in group E was better than that in group G ( P<0.05). The incidence of hypoxemia, restlessness, nausea and vomiting in group E was lower than that in group G (all P<0.05). Conclusions:Ultrasound-guided bilateral erector spinal nerve block can effectively reduce postoperative pain and complications of NUSS in children with pectus excavatum, and can also reduce the amount of sufentanil used during the operation, improve the sleep quality after the operation, which is conducive to the recovery of children, and is worthy of promotion.
