Air Embolism-Induced Ischemic Stroke Following Orthognathic Surgery in a Patient With Goldenhar Syndrome.

Goldenhar syndrome, a rare congenital anomaly, manifests as craniofacial malformations often necessitating intricate surgical interventions. These procedures, though crucial, can expose patients to diverse postoperative complications, including hemorrhage or infection. A noteworthy complication is stroke, potentially linked to air embolism or local surgical trauma. We highlight a case of a male patient, aged 20 years, who experienced a significant postoperative complication of an ischemic stroke, theorized to be due to an air embolism, after undergoing orthognathic procedures for Goldenhar syndrome. The patient was subjected to LeFort I maxillary osteotomy, bilateral sagittal split ramus osteotomy of the mandible, and anterior iliac crest bone grafting to the right maxilla. He suffered an acute ischemic stroke in the left thalamus post-surgery, theorized to stem from an air embolism. Advanced imaging demonstrated air pockets within the cavernous sinus, a rare and concerning finding suggestive of potential air embolism. This case underscores the intricate challenges in treating Goldenhar syndrome patients and the rare but significant risk of stroke due to air embolism or surgical trauma. Limited literature on managing air embolism complications specific to Goldenhar syndrome surgeries exists. Generally, management includes immediate recognition, positional adjustments, air aspiration via central venous catheters, hyperbaric oxygen therapy, hemodynamic support, and high-flow oxygen administration to expedite air resorption. Our patient was conservatively managed post-surgery, and at a 3-month neurology follow-up, he showed significant improvement with only residual right arm weakness. It emphasizes the imperative of a comprehensive, multidisciplinary approach.

Study protocol for the Intraoperative Complications Assessment and Reporting with Universal Standards (ICARUS) global cross-specialty surveys and consensus.

Annually, about 300 million surgeries lead to significant intraoperative adverse events (iAEs), impacting patients and surgeons. Their full extent is underestimated due to flawed assessment and reporting methods. Inconsistent adoption of new grading systems and a lack of standardization, along with litigation concerns, contribute to underreporting. Only half of relevant journals provide guidelines on reporting these events, with a lack of standards in surgical literature. To address these issues, the Intraoperative Complications Assessment and Reporting with Universal Standard (ICARUS) Global Surgical Collaboration was established in 2022. The initiative involves conducting global surveys and a Delphi consensus to understand the barriers for poor reporting of iAEs, validate shared criteria for reporting, define iAEs according to surgical procedures, evaluate the existing grading systems' reliability, and identify strategies for enhancing the collection, reporting, and management of iAEs. Invitation to participate are extended to all the surgical specialties, interventional cardiology, interventional radiology, OR Staffs and anesthesiology. This effort represents an essential step towards improved patient safety and the well-being of healthcare professionals in the surgical field.

Analysis of factors affecting intraoperative hemorrhage during percutaneous nephrolithotomy and establishment of nomogram model.

Intraoperative hemorrhage is an important factor affecting intraoperative safety and postoperative patient recovery in percutaneous nephrolithotomy (PCNL). This study aimed to identify the factors that influence intraoperative hemorrhage during PCNL and develop a predictive nomogram model based on these factors.A total of 118 patients who underwent PCNL at the Department of Urology, The Affiliated Huai'an No.1 People's Hospital of Nanjing Medical University from January 2021 to September 2023 was included in this study. The patients were divided into a hemorrhage group (58 cases) and a control group (60 cases) based on the decrease in hemoglobin levels after surgery. The clinical data of all patients were collected, and both univariate analysis and multivariate logistic regression analysis were conducted to identify the independent risk factors for intraoperative hemorrhage during PCNL. The independent risk factors were used to construct a nomogram model using R software. Additionally, receiver operating characteristic (ROC) curves, calibration curves and decision curve analysis (DCA) were utilized to evaluate the model.Multivariate logistic regression analysis revealed that diabetes, long operation time and low psoas muscle mass index (PMI) were independent risk factors for intraoperative hemorrhage during PCNL (P < 0.05). A nomogram model was developed incorporating these factors, and the areas under the ROC curve (AUCs) in the training set and validation set were 0.740 (95% CI: 0.637-0.843) and 0.742 (95% CI: 0.554-0.931), respectively. The calibration curve and Hosmer-Lemeshow test (P = 0.719) of the model proved that the model was well fitted and calibrated. The results of the DCA showed that the model had high value for clinical application.Diabetes, long operation time and low PMI were found to be independent risk factors for intraoperative hemorrhage during PCNL. The nomogram model based on these factors can be used to predict the risk of intraoperative hemorrhage, which is beneficial for perioperative intervention in high-risk groups to improve the safety of surgery and reduce the incidence of postoperative complications.

Epidemiological Predictors of Financial Toxicity in Surgical Burn Injuries: A Multicenter, Longitudinal, Cohort Study.

BACKGROUND: Burns constitute a major global health challenge, causing over 11 million injuries and 300,000 deaths annually and surpassing the economic burden of cervical cancer and HIV combined. Despite this, patient-level financial consequences of burn injuries remain poorly quantified, with a significant gap in data from low- and middle-income countries. In this study, we evaluate financial toxicity in burn patients. METHODS: A prospective, multicenter cohort study was conducted across two tertiary care hospitals in India, assessing 123 adult surgical in-patients undergoing operative interventions for burn injuries. Patient sociodemographic, clinical, and financial data were collected through surveys and electronic records during hospitalization and at 1, 3, and 6 months postoperatively. Out-of-pocket costs (OOPCs) for surgical burn treatment were evaluated during hospitalization. Longitudinal changes in income, employment status, and affordability of basic subsistence needs were assessed at the 1-, 3-, and 6-month postoperative time point. Degree of financial toxicity was calculated using a combination of the metrics catastrophic health expenditure and financial hardship. Development of financial toxicity was compared by sociodemographic and clinical characteristics using logistic regression models. RESULTS: Of the cohort, 60% experienced financial toxicity. Median OOPCs was US$555.32 with the majority of OOPCs stemming from direct nonmedical costs (US$318.45). Cost of initial hospitalization exceeded monthly annual income by 80%. Following surgical burn care, income decreased by US$318.18 within 6 months, accompanied by a 53% increase in unemployment rates. At least 40% of the cohort consistently reported inability to afford basic subsistence needs within the 6-month perioperative period. Significant predictors of developing financial toxicity included male gender (odds ratio, 4.17; 95% confidence interval, 1.25-14.29; P = 0.02) and hospital stays exceeding 20 days (odds ratio, 11.17; 95% confidence interval, 2.11-59.22; P ≤ 0.01). CONCLUSIONS: Surgical treatment for burn injuries is associated with substantial financial toxicity. National and local policies must expand their scope beyond direct medical costs to address direct nonmedical and indirect costs. These include burn care insurance, teleconsultation follow-ups, hospital-affiliated subsidized lodging, and resources for occupational support and rehabilitation. These measures are crucial to alleviate the financial burden of burn care, particularly during the perioperative period.

SUCCOR morbidity: complications in minimally invasive versus open radical hysterectomy in early cervical cancer.

OBJECTIVE: The aim of this study was to compare the incidence of intra-operative and post-operative complications in open and minimally invasive radical hysterectomy for patients with early-stage cervical cancer. METHODS: Data were collected from the SUCCOR database of 1272 patients with stage IB1 cervical cancer (International Federation of Gynecology and Obstetrics (FIGO), 2009) who underwent radical hysterectomy in Europe between January 2013 and December 2014. We reviewed the duration of the surgeries, estimated blood loss, length of hospital stay, intra-operative and post-operative complications. The inclusion criteria were age ≥18 years and histologic type (squamous cell carcinoma, adenocarcinoma, or adenosquamous carcinoma). Pelvic MRI confirming a tumor diameter ≤4 cm with no parametrial invasion and a pre-operative CT scan, MRI, or positron emission tomography CT demonstrating no extra-cervical metastatic disease were mandatory. Outcomes of interest were any grade >3 adverse events, intra-operative adverse events, post-operative adverse events, length of hospital stay, length of operation, and blood loss. RESULTS: The study included 1156 patients, 633 (54%) in the open surgery group and 523 (46%) in the minimally invasive surgery group. Median age was 46 years (range 18-82), median body mass index 25 kg/m2 (range 15-68), and 1022 (88.3%) patients were considered to have an optimal performance status (ECOG Performance Status 0). The most common histologic tumor type was squamous carcinoma (n=794, 68.7%) and the most frequent FIGO staging was IB1 (n=510, 44.1%). In the minimally invasive surgery group the median duration of surgery was longer (240 vs 187 min, p<0.01), median estimated blood loss was lower (100 vs 300 mL, p<0.01), and median length of hospital stay was shorter (4 vs 7 days, p<0.01) compared with the abdominal surgery group. There was no difference in the overall incidence of intra-operative and post-operative complications between the two groups. Regarding grade I complications, the incidence of vaginal bleeding (2.9% vs 0.6%, p<0.01) and vaginal cuff dehiscence was higher in the minimally invasive surgery group than in the open group (3.3% vs 0.5%, p<0.01). Regarding grade III post-operative complications, bladder dysfunction (1.3% vs 0.2%, p=0.046) and abdominal wall infection (1.1% vs 0%, p=0.018) were more common in the open surgery group than in the minimally invasive surgery group. Ureteral fistula was more frequent in the minimally invasive group than in the open surgery group (1.7% vs 0.5%, p=0.037). CONCLUSION: Our study showed that there was no significant difference in the overall incidence of intra-operative and post-operative complications between minimally invasive radical hysterectomy and the open approach.

Peripheral perfusion index stratifies risk in patients with intraoperative anemia: A multicentre cohort study.

STUDY OBJECTIVE: Evidence for red blood cell (RBC) transfusion thresholds in the intraoperative setting is limited, and current perioperative recommendations may not correspond with individual intraoperative physiological demands. Hemodynamics relevant for the decision to transfuse may include peripheral perfusion index (PPI). The objective of this prospective study was to assess the associations of PPI and hemoglobin levels with the risk of postoperative morbidity and mortality. DESIGN: Multicenter cohort study. SETTING: Bispebjerg and Hvidovre University Hospitals, Copenhagen, Denmark. PATIENTS: We included 741 patients who underwent acute high risk abdominal surgery or hip fracture surgery. INTERVENTIONS: No interventions were carried out. MEASUREMENTS: Principal values collected included measurements of peripheral perfusion index and hemoglobin values. METHODS: The study was conducted using prospectively obtained data on adults who underwent emergency high-risk surgery. Subjects were categorized into high vs. low subgroups stratified by pre-defined PPI levels (PPI: > 1.5 vs. < 1.5) and Hb levels (Hb: > 9.7 g/dL vs. < 9.7 g/dL). The study assessed mortality and severe postoperative complications within 90 days. MAIN RESULTS: We included 741 patients. 90-day mortality was 21% (n = 154), frequency of severe postoperative complications was 31% (n = 231). Patients with both low PPI and low Hb had the highest adjusted odds ratio for both 90-day severe postoperative complications (2.95, [1.62-5.45]) and 90-day mortality (3.13, [1.45-7.11]). A comparison of patients with low PPI and low Hb to those with high PPI and low Hb detected significantly higher 90-day mortality risk in the low PPI and low Hb group (OR 8.6, [1.57-162.10]). CONCLUSION: High PPI in acute surgical patients who also presents with anemia was associated with a significantly better outcome when compared with patients with both low PPI and anemia. PPI should therefore be further investigated as a potential parameter to guide intraoperative RBC transfusion therapy.

Peri- and post-operative outcomes of robot-assisted radical cystectomy after the implementation of the EAU guidelines recommendations for collecting and reporting complications at a high-volume referral center.

PURPOSE: No studies relied on a standardized methodology to collect postoperative complications after robot-assisted radical cystectomy (RARC). The aim of our study was to evaluate peri- and post-operative outcomes of patients undergoing RARC adhering to the European Association of Urology (EAU) recommendations for reporting surgical outcomes and using a long postoperative follow-up. MATERIALS AND METHODS: 246 patients who underwent RARC with intracorporal urinary diversion at a single tertiary referral center with a postoperative follow-up ≥ 1 year for survivors. Postoperative outcomes were collected prospectively by interviews done by medical doctors. Complications were scored using the Clavien-Dindo classification (CD), grouped by type and severity (severe: CD score ≥ 3). We described peri- and post-operative outcomes and complication chronological distribution. RESULTS: Overall, 16 (6.5%) and 225 patients (91%) experienced intraoperative and postoperative complications, respectively. Moreover, 139 (57%) experienced severe complications. The most common any-grade and severe complications were infectious (72%) and genitourinary (35%), respectively. Overall, 52% of complications (358/682) occurred within 10 days from surgery, and 51% of severe complications (106/207) occurred within 35 days. However, 13% of complications (90/682) and 28% of severe complications (59/207) occurred 3 months after surgery. The earliest complications were fever of unknown origins and paralytic ileus (median time-to-complication [mTTC]: 4 days), the latest complications were urinary tract infection (mTTC: 40 days) and hydronephrosis/ureteral obstruction (mTTC: 70 days). CONCLUSIONS: The rate of postoperative complications after RARC is > 90% when a standardized collection method and a long follow-up is implemented. These results should be used to identify potential areas of improvement and for preoperative patient counseling.

Prevention of esophageal lesions during atrial fibrillation catheter ablation using esophageal temperature monitoring: A systematic review and meta-analysis.

INTRODUCTION: The use of esophageal temperature monitoring (ETM) for the prevention of esophageal injury during atrial fibrillation (AF) ablation is often advocated. However, evidence supporting its use is scarce and controversial. We therefore aimed to review the evidence assessing the efficacy of ETM for the prevention of esophageal injury. METHODS: We performed a meta-analysis and systematic review of the available literature from inception to December 31, 2022. All studies comparing the use of ETM, versus no ETM, during radiofrequency (RF) AF ablation and which reported the incidence of endoscopically detected esophageal lesions (EDELs) were included. RESULTS: Eleven studies with a total of 1112 patients undergoing RF AF ablation were identified. Of those patients, 627 were assigned to ETM (56%). The overall incidence of EDELs was 9.8%. The use of ETM during AF ablation was associated with a non significant increase in the incidence of EDELs (12.3% with ETM, vs. 6.6 % without ETM, odds ratio, 1.44, 95%CI, 0.49, 4.22, p = .51, I2 = 72%). The use of ETM was associated with a significant increase in the energy delivered specifically on the posterior wall compared to patients without ETM (mean power difference: 5.13 Watts, 95% CI, 1.52, 8.74, p = .005). CONCLUSIONS: The use of ETM does not reduce the incidence of EDELs during RF AF ablation. The higher energy delivered on the posterior wall is likely attributable to a false sense of safety that may explain the lack of benefit of ETM. Further randomized controlled trials are needed to provide conclusive results.

Intraoperative adverse events among surgeons in Singapore: a multicentre cross-sectional study on impact and support.

BACKGROUND: It is known that many surgeons encounter intraoperative adverse events which can result in Second Victim Syndrome (SVS), with significant detriment to their emotional and physical health. There is, however, a paucity of Asian studies in this space. The present study thus aimed to explore the degree to which the experience of an adverse event is common among surgeons in Singapore, as well as its impact, and factors affecting their responses and perceived support systems. METHODS: A self-administered survey was sent to surgeons at four large tertiary hospitals. The 42-item questionnaire used a systematic closed and open approach, to assess: Personal experience with intraoperative adverse events, emotional, psychological and physical impact of these events and perceived support systems. RESULTS: The response rate was 57.5% (n = 196). Most respondents were male (54.8%), between 35 and 44 years old, and holding the senior consultant position. In the past 12 months alone, 68.9% recalled an adverse event. The emotional impact was significant, including sadness (63.1%), guilt (53.1%) and anxiety (45.4%). Speaking to colleagues was the most helpful support source (66.7%) and almost all surgeons did not receive counselling (93.3%), with the majority deeming it unnecessary (72.2%). Notably, 68.1% of the surgeons had positive takeaways, gaining new insight and improving vigilance towards errors. Both gender and surgeon experience did not affect the likelihood of errors and emotional impact, but more experienced surgeons were less likely to have positive takeaways (p = 0.035). Individuals may become advocates for patient safety, while simultaneously championing the cause of psychological support for others. CONCLUSIONS: Intraoperative adverse events are prevalent and its emotional impact is significant, regardless of the surgeon's experience or gender. While colleagues and peer discussions are a pillar of support, healthcare institutions should do more to address the impact and ensuing consequences.

Risk factors for diaphragmatic injury in subxiphoid video-assisted thoracoscopic surgery.

BACKGROUND: Subxiphoid video-assisted thoracoscopic surgery (VATS) is considered a safe and feasible operation for anterior mediastinal mass resection. However, diaphragmatic injury, presented as tearing or puncturing, may occur during subxiphoid VATS despite of low incidence. This study aims to explore risk factors for diaphragmatic injury in subxiphoid VATS, as well as strategies to reduce occurrence of the injury. METHODS: We retrospectively reviewed clinical records of 44 consecutive adult patients who underwent subxiphoid VATS. These patients were divided into two groups: diaphragmatic injury group and non-injury group. Perioperative outcomes and anatomic features derived from 3D CT reconstructions were compared between the two groups. RESULTS: Significant differences were observed in operation time (223.25 ± 92.57 vs. 136.28 ± 53.05, P = 0.006), xiphoid length (6.47 ± 0.85 vs. 4.79 ± 1.04, P = 0.001) and length of the xiphoid below the attachment point on the diaphragm (24.86 ± 12.02 vs. 14.61 ± 9.25, P = 0.029). Odds ratio for the length of the xiphoid below the attachment point on the diaphragm was 1.09 (1.001-1.186), P = 0.048 by binary logistic regression analysis. CONCLUSIONS: We identified the length of the xiphoid below the attachment point on the diaphragm as an independent risk factor for diaphragm injury during subxiphoid VATS. Prior to subxiphoid VATS, a 3D chest CT reconstruction is recommended to assess the patients' anatomic variations within the xiphoid process. For patients with longer xiphoid process, a higher incision at the middle and upper part of the xiphoid process, and partial xiphoid process resection or xiphoidectomy is preferred.

Evaluation of the early use of norepinephrine in major abdominal surgery on medical and surgical postoperative complications: study protocol for a randomised controlled trial (EPON STUDY).

BACKGROUND: Post-induction anaesthesia often promotes intraoperative hypotension (IOH) that can worsen postoperative outcomes. This study aims to assess the benefit of norepinephrine versus ephedrine at the induction of anaesthesia to prevent postoperative complications following major abdominal surgery by preventing IOH. METHODS AND ANALYSIS: The EPON STUDY is a prospective single-centre randomised controlled trial with the planned inclusion of 500 patients scheduled for major abdominal surgery at the Amiens University Hospital. The inclusion criteria are patients aged over 50 years weighing more than 50 kg with an American Society of Anesthesiologists physical status score of ≥2 undergoing major abdominal surgery under general anaesthesia. Patients are allocated either to the intervention group (n=250) or the standard group (n=250). In the intervention group, the prevention of post-induction IOH is performed with norepinephrine (dilution to 0.016 mg/mL) using an electric syringe pump at a rate of 0.48 mg/h (30 mL/h) from the start of anaesthesia and then titrated to achieve the haemodynamic target. In the control group, the prevention of post-induction IOH is performed with manual titration of ephedrine, with a maximal dose of 30 mg, followed by perfusion with norepinephrine. In both groups, the haemodynamic target to maintain is a mean arterial pressure (MAP) of 65 mm Hg or 70 mm Hg for patients with a medical history of hypertension. An intention-to-treat analysis will be performed. The primary outcome is the Clavien-Dindo score assessed up to 30 days postoperatively. The secondary endpoints are the length of hospital stay and length of stay in an intensive care unit/postoperative care unit; postoperative renal function; postoperative cardiovascular, respiratory, neurological, haematological and infectious complications at 1 month; and volume of intraoperative vascular filling and mortality at 1 month. ETHICS AND DISSEMINATION: Ethical approval was obtained from the committee of protection of the persons of Ile de France in May 2021 (number 21 05 41). The authors will be involved in disseminating the research findings (through attending conferences and co-authoring papers). The results of the study will be disseminated via peer-reviewed publications and presentations at national and international conferences. TRIAL REGISTRATION NUMBER: NCT05276596.

Machine learning model based on RCA-PDCA nursing methods and differentiating factors to predict hypotension during cesarean section surgery.

BACKGROUND: Intraoperative hypotension during cesarean section has become a serious complication for maternal and fetal healthy. It is commonly encountered by subarachnoid anesthesia. However, currently used control methods have varying degrees of side effects, such as drugs. The Root Cause Analysis (RCA) - Plan, Do, Check, Act (PDCA) is a new model of care that identifies the root causes of problems. The study aimed to demonstrate the usefulness of RCA-PDCA nursing methods in preventing intraoperative hypotension during cesarean section and to predict the occurrence of intraoperative hypotension through a machine learning model. METHODS: Patients who underwent cesarean section at Traditional Chinese Medicine of Southwest Medical University from January 2023 to December 2023 were retrospectively screened, and the data of their gestational times, age, height, weight, history of allergies, intraoperative vital signs, fetal condition, operative time, fluid out and in, adverse effects, use of vasopressor drugs, anxiety-depression-pain scores, and satisfaction were collected and analyzed. The statistically different features were screened and five machine learning models were used as predictive models to assess the usefulness of the RCA-PDCA model of care. RESULTS: (1) Compared with the general nursing model, the RCA-PDCA nursing model significantly reduces the incidence of intraoperative hypotension and postoperative complications in cesarean delivery, and the patient experience is comfortable and satisfactory. (2) Among the five machine learning models, the RF model has the best predictive performance, and the accuracy of the random forest model in preventing intraoperative hypotension is as high as 90%. CONCLUSION: Through computer machine learning model analysis, we prove the importance of the RCA-PDCA nursing method in the prevention of intraoperative hypotension during cesarean section, especially the Random Forest model which performed well and promoted the application of artificial intelligence computer learning methods in the field of medical analysis.

Risk Factors of Intraoperative Pressure Injury in Adult Patients Undergoing Neurologic Surgery.

GENERAL PURPOSE: To present research investigating the incidence of and risk factors associated with intraoperative pressure injury in patients undergoing neurologic surgery at Xiangya Hospital, Central South University in China. TARGET AUDIENCE: This continuing education activity is intended for physicians, physician assistants, nurse practitioners, and registered nurses with an interest in skin and wound care. LEARNING OBJECTIVES/OUTCOMES: After participating in this educational activity, the participant will:1. Identify the incidence of intraoperative pressure injuries (PIs) in patients undergoing neurologic surgery at Xiangya Hospital, Central South University in China.2. Describe risk factors for intraoperative PI.3. Outline strategies to help mitigate intraoperative PI risk.

Intraoperative pressure injury (PI) development is an adverse event that impacts thousands of patients globally and is associated with extended hospital stays and increased risk of mortality. To investigate the incidence of intraoperative PI in patients undergoing neurologic surgery and identify associated risk factors. A total of 1,728 patients who underwent neurosurgery in Xiangya Hospital, Central South University between January 2021 and December 2022 were included in this retrospective study. The authors collected patients' demographic data and clinical characteristics and used univariate and multivariate regression to evaluate significant PI risk factors. Intraoperative PI was observed in 1.8% of all surgical cases (n = 31). Having a body mass index greater than 24 kg/m2 (odds ratio, 3.87; 95% CI, 1.62­9.23; P = .002), being in a lateral position (odds ratio, 2.53; 95% CI, 1.04­6.17; P = .042) or a prone position (odds ratio, 10.43; 95% CI, 3.37­32.23; P < .001), and having a longer operation time (cutoff point at 7.92 hours for increased risk of PI; odds ratio, 1.36; 95% CI, 1.21­1.53; P < .001) were significant risk factors for intraoperative PI. This study identified three independent risk factors for intraoperative PI development: body position, surgery duration, and high body mass index. These findings can help OR nurses identify patients who are vulnerable to intraoperative PI and provide appropriate preventive measures. For these patients, perioperative protection and frequent microrepositioning during surgery would be indispensable.

Operative efficiency: a comparative analysis of Versius and da Vinci robotic systems in abdominal surgery.

Robotic-assisted surgery has gained momentum in the pursuit of improved minimally invasive procedures. The adoption of new robotic platforms, such as the Versius, raises concerns about safety, efficacy, and learning curves. This study compares the Versius to the well-established da Vinci in terms of operative time and patient population. Retrospective data collection was conducted on patient data from inguinal hernia surgery, ventral hernia surgery, and cholecystectomies performed between February 2022 and March 2023 at the American Hospital of Dubai. Only experienced cases were included, ensuring proficiency with robotic technology. Versius had longer procedure times in inguinal and ventral hernia surgeries but not in cholecystectomy. No intraoperative complications were observed in either system. This study demonstrates that Versius can provide comparable outcomes to the da Vinci in abdominal surgery, with no observed intraoperative complications.

The practical and educational value of scleral buckling with chandelier illumination.

PURPOSE: To compare the surgical results in cases of primary rhegmatogenous retinal detachments between standard scleral buckling (SSB) and scleral buckling with chandelier illumination (SBC) and to analyse the differences in SBC surgical results between an experienced ophthalmologist and inexperienced ophthalmologists. METHODS: Consecutive surgical case series of 155 eyes that underwent scleral buckling were retrospectively reviewed and divided into four groups: SSB performed by an experienced ophthalmologist (n = 54), SBC performed by an experienced ophthalmologist (n = 52), SBC performed by inexperienced ophthalmologists (n = 40) and SSB performed by inexperienced ophthalmologists (n = 9). Then, these four groups were compared. RESULTS: No significant differences were observed between SSB and SBC procedures both performed by the experienced ophthalmologist with regard to demographics, preoperative findings, contents of the surgery, intraoperative complications, retinal reattachment, postoperative findings and postoperative complications. Between SBC performed by the experienced ophthalmologist and SBC performed by the inexperienced ophthalmologists, no significant differences were found regarding intraoperative complications, retinal reattachment, postoperative findings and postoperative complications. Between SSB and SBC procedures both performed by the inexperienced ophthalmologist, a significant difference was found regarding intraoperative complications. CONCLUSION: There were no significant differences in surgical results between SSB and SBC when both were performed by the experienced ophthalmologist. In addition, the surgical results were equal between the experienced ophthalmologist and the inexperienced ophthalmologist as far as SBC was concerned. Learning scleral buckling skills by using SBC is a reasonable course of action for inexperienced ophthalmologists.

Factors Influencing the Occurrence of Intraoperative Hypothermia in Patients Undergoing General Anesthesia Intervention: A Study in a Tertiary Care Hospital.

BACKGROUND Intraoperative and postoperative hypothermia of patients can be caused by the use of anesthetic drugs and the complicated and time-consuming procedures of interventional surgery. This retrospective study included 184 patients to investigate the incidence and factors associated with hypothermia during intraoperative anesthesia in a single center in China between January and October 2023. MATERIAL AND METHODS A convenient sampling method was used to select 184 patients who underwent general anesthesia intervention in a tertiary hospital in Sichuan Province from January to October 2023 as the study population. The independent factors influencing the occurrence of intraoperative hypothermia were analyzed. A survey was conducted to collect 5 demographic factors, 4 preoperative-related factors, and 10 surgically related factors. According to the occurrence of intraoperative hypothermia, the independent influencing factors of unplanned hypothermia during perioperative period were further analyzed. RESULTS Among 184 patients, 64 (34.78%) experienced perioperative unplanned hypothermia, of which 5 (7.81%) cases occurred before the start of surgery, 7 (10.94%) occurred before the start of surgery after anesthesia, and 52 (81.25%) occurred during surgery. Logistic regression analysis showed that body temperature at the beginning of surgery (P<0.001), set operating room temperature (P<0.001), duration of anesthesia (P=0.006), and age (P=0.001) were independent influencing factors for unplanned hypothermia during perioperative period. CONCLUSIONS The incidence of intraoperative hypothermia is high in patients undergoing general anesthesia interventions. Age, duration of anesthesia, set operating room temperature, and body temperature at the beginning of the operation were independent influencing factors for the occurrence of unplanned hypothermia during the perioperative period.

Gasless transvaginal natural orifice transluminal endoscopic surgery for hysterectomy and salpingectomy on a robot platform with flexible devices in a porcine model.

In this report, we described a new technique of gasless V-NOTES for hysterectomy and salpingectomy on a robotic platform with flexible devices in a porcine model. As a result, the gynecological procedures were successfully completed. The total operative time was 110 min, while the docking time was 10 min. The estimated blood loss was estimated to be 10 mL with no intraoperative complications. It revealed that gasless V-NOTES for hysterectomy and salpingectomy on a robotic platform with flexible devices appeared to be feasible and safe in the porcine model and has the potential for clinical use in human beings.

A Novel Surgical Indication for Scheuermann's Kyphosis.

Scheuermann kyphosis can be treated surgically to restore proper sagittal alignment. Thoracic curves >70° are typically indicated for surgical intervention. However, patients who have reached their natural limit of compensatory lumbar hyperlordosis are at risk of accelerated degeneration. This can be determined by comparing lumbar lordosis on standing neutral radiographs and supine extension radiographs. Minimal additional lordosis in extension compared with neutral, abutment of the spinous processes, or greater lumbar lordosis standing than with attempted extension suggest the patient is maximally compensated. We present a case of an adolescent boy with Scheuermann kyphosis who had reached the limit of his hyperlordosis compensation reserve. He subsequently underwent a T4 to L2 posterior spinal fusion with T7 to T11 Ponte Smith-Petersen grade two osteotomies. He tolerated the procedure well with no intraoperative complications or neuromonitoring changes. The patient has continued to do well and progressed to normal activity at 5-month follow-up.
