Balanced opioid-free anesthesia with lidocaine and esketamine versus balanced anesthesia with sufentanil for gynecological endoscopic surgery: a randomized controlled trial

In this randomized controlled trial, 74 patients scheduled for gynecological laparoscopic surgery (American Society of Anesthesiologists grade I/II) were enrolled and randomly divided into two study groups: (i) Group C (control), received sufentanil (0.3 μg/kg) and saline, followed by sufentanil (0.1 μg/kg∙h) and saline; and (ii) Group F (OFA), received esketamine (0.15 mg/kg) and lidocaine (2 mg/kg), followed by esketamine (0.1 mg/kg∙h) and lidocaine (1.5 mg/kg∙h). The primary outcome was the 48-h time-weighted average (TWA) of postoperative pain scores. Secondary outcomes included time to extubation, adverse effects, and postoperative sedation score, pain scores at different time points, analgesic consumption at 48 h, and gastrointestinal functional recovery. The 48-h TWAs of pain scores were 1.32 (0.78) (95% CI 1.06–1.58) and 1.09 (0.70) (95% CI 0.87–1.33) for Groups F and C, respectively. The estimated difference between Groups F and C was − 0.23 (95% CI − 0.58 − 0.12; P = 0.195). No differences were found in any of the secondary outcomes and no severe adverse effects were observed in either group. Balanced OFA with lidocaine and esketamine achieved similar effects to balanced anesthesia with sufentanil in patients undergoing elective gynecological laparoscopic surgery, without severe adverse effects.Clinical Trial Registration: ChiCTR2300067951, www.chictr.org.cn 01 February, 2023.

Effects of Postoperative Gum Chewing on Recovery of Gastrointestinal Function Following Laparoscopic Gynecologic Surgery: Systematic Review and Meta-Analysis of Randomized Controlled Trials.

Background: Chewing gum, considered a form of sham feeding, has been shown to improve intestinal motor and secretory function in various types of abdominal surgery. We conducted this systematic review to evaluate the effects of postoperative gum chewing on the recovery of gastrointestinal function after laparoscopic gynecologic surgery. Methods: We performed a comprehensive literature review of all randomized controlled trials (RCTs) in PubMed, Embase, and a reference list of relevant studies from the inception to 11 March 2024, comparing postoperative gum chewing versus no gum chewing following laparoscopic gynecologic surgery regardless of indications and setting without language restriction. The primary outcome was the time to the presence of bowel sounds and the time to the first passage of flatus. Cochrane's risk of bias tool was used to assess the risk of bias in included studies. Results: Nine RCTs with a total of 1011 patients were included. Overall, three studies were categorized as having a low risk of bias, three had some concerns, and three exhibited a high risk of bias. The time to the presence of bowel sounds (mean difference [MD] -2.66 h, 95% confidence interval [CI] -3.68 to -1.64, p < 0.00001) and time to the first passage of flatus (MD -4.20 h, 95% CI -5.79 to -2.61, p < 0.00001) was significantly shorter in the gum-chewing group. There was no statistical difference between the two groups with regard to the time to the first defecation (MD -6.52 h, 95% CI -15.70 to 2.66, p = 0.16), time to the first postoperative mobilization (MD 24.05 min, 95% CI -38.16 to 86.26, p = 0.45), postoperative ileus (MD 0.68, 95% CI 0.39 to 1.19, p = 0.17), and length of hospital stay (MD -0.05 day, 95% CI -0.14 to 0.04, p = 0.28). Conclusions: Gum chewing following laparoscopic gynecologic surgery appears to promote the recovery of gastrointestinal function, as evidenced by a reduced time to the presence of bowel sounds and the first passage of flatus.

Effect of continuous measurement and adjustment of endotracheal tube cuff pressure on postoperative sore throat in patients undergoing gynecological laparoscopic surgery: a randomized controlled trial.

Postoperative sore throat (POST) is a common complication following endotracheal tube removal, and effective preventive strategies remain elusive. This trial aimed to determine whether actively regulating intraoperative cuff pressure below the tracheal capillary perfusion pressure threshold could effectively reduce POST incidence in patients undergoing gynecological laparoscopic procedures. This single-center, randomized controlled superiority trial allocated 60 patients scheduled for elective gynecological laparoscopic procedures into two groups: one designated for cuff pressure measurement and adjustment (CPMA) group, and a control group where only cuff pressure measurement was conducted without any subsequent adjustments. The primary outcome was POST incidence at rest within 24h post-extubation. Secondary outcomes included cough, hoarseness, postoperative nausea and vomiting (PONV) incidence, and post-extubation pain severity. The incidence of sore throat at rest within 24h after extubation in the CPMA group was lower than in the control group, meeting the criteria for statistically significant superiority based on a one-sided test (3.3% vs. 26.7%, P < 0.025). No statistically significant differences were observed in cough, hoarseness, or pain scores within 24h post-extubation between the two groups. However, the CPMA group had a higher incidence of PONV compared to the control group. Additionally, the control group reported higher sore throat severity scores within 24h post-extubation. Continuous monitoring and maintenance of tracheal tube cuff pressure at 18 mmHg were superior to merely monitoring without adjustment, effectively reducing the incidence of POST during quiet within 24h after tracheal tube removal in gynecological laparoscopic surgery patients. The study was registered at www.chictr.org.cn (ChiCTR2200064792) on 18/10/2022.

Safety, Efficacy, and Cost-effectiveness of Organ Suspension in Laparoscopic Gynecologic Surgery. A Retrospective Cohort Study to Validate an Innovative Technique: Laparoscopic Organ Suspension sec. Angioni.

This study aims to evaluate the safety, efficacy, and cost-effectiveness of the Laparoscopic Organ Suspension sec. Angioni, an innovative approach to transient organ suspension (OS) in laparoscopic gynecological procedures. Recognizing the need to enhance surgical site access and overcome limitations of existing organ retraction methods, the study investigates a novel, in-theatre constructed OS device. This retrospective observational study was conducted from March 2019 to May 2021 and included 330 patients who underwent multiport or single-site-port laparoscopic surgery employing Angioni's Technique for transient pelvic organ suspension. Participants included individuals undergoing surgery for conditions such as endometriosis, ovarian cancer, endometrial cancer, pelvic prolapse, and benign ovarian cysts. The Laparoscopic Organ Suspension sec. Angioni utilizes a segment of a Foley catheter connected to a Polyglactin suture to provide adjustable tension, minimizing the need for reconfiguration during surgery. The application of this OS technique resulted in an average suspension time of 1.9 minutes, with no significant difference between senior and junior surgeons. The method proved more time-efficient for posterior peritoneum suspension than other published methods and showed no additional risks of organ damage, bleeding, conversion to laparotomy, or OS-related complications. The secondary outcomes revealed reduced hospital stays and minimal blood loss, highlighting the procedure's overall efficiency. Given its retrospective and single-center nature, the study's results may not be widely generalizable. Prospective multicentric comparative studies are recommended to to further validate the Angioni's Technique. Laparoscopic Organ Suspension sec. Angioni is introduced as a straightforward, safe, and cost-effective method that significantly streamlines the surgical process. Its adaptability and ease of use suggest that it could be a valuable addition to current gynecological surgical practices, with potential implications for increasing efficiency and reducing procedural costs. Future studies are required to confirm these results across diverse clinical environments.

Surgical Considerations for Minimally Invasive Gynecologic Surgery in Patient with Skeletal Dysplasia

Skeletal dysplasias are a group of heritable diseases in which the bone and cartilage are affected. Despite their impact in anatomical structures, there are many gaps in knowledge between the relationship between skeletal dysplasias and minimal invasive gynecologic surgery. Here, we present a case of a 44-year-old patient with a history of skeletal dysplasia and abnormal uterine bleeding, due to uterine fibroids. As medical treatment failed, a laparoscopic surgery was performed. As expected, normal anatomical landmarks used in laparoscopy were lost as a result of severe scoliosis.Despite anesthesic and surgical difficulties, a successful total laparoscopic hysterectomy and bilateral salpingectomy was performed. Patients with these disorders need to have an individualized and interdisciplinary approach in gynecologic laparoscopic surgery

Implementation and Evaluation of a Uterine Manipulation System Incorporated with an Existing Tiltable-Tip Uterine Manipulator for Gynecological Laparoscopy

In gynecologic surgery, a uterine manipulator is one of the instruments used to perform the laparoscopy. Throughout the past decade, a number of robotic technology applications used for uterine manipulation during surgery have been designed with the aim of increasing the efficiency, improving the precision, and reducing the workload of medical assistants. Although the RCM (Remote Center of Motion) mechanism is one of the key features in a Minimally Invasive Surgical (MIS) robot, the preliminary result in this study, in which the RCM mechanism was applied in a uterine manipulation robot, proved that this may cause unpleasant sensations such as irritation or harm to the nearby area during such manipulation. Therefore, a design of a non-RCM 2-DoF (Degree of Freedom) Robotic Uterine Manipulation System, in cooperation with an existing, reusable and tiltable-tip uterine manipulator, for laparoscopic gynecologic surgery has been proposed and evaluated via a mathematical model along with numerical analysis, a 3D uterus model, and a 1:1 uterus manikin model in order to demonstrate the use of the essential functions. According to the experimental results, the maximum load of 500 g has been handled well by the prototype, with the movement ranges of ±150° in the roll panel and ±90° in the pitch panel (0∼90° for anteversion and 0∼−90° for retroversion, if needed, which can be achieved by rotating the instrument to the other side). Furthermore, to verify this new design prior to its use on patients, and also in consideration of the ethics of human experimentation, through extensive testing on five donated soft-tissue cadavers, the proposed robot received positive feedback from all five surgeons performing the experiments and could offer effective uterine manipulation at the angular velocity of 4 °/s (0.67 RPM) with steady delineation of the vaginal fornices to create necessary motions in the pitch and roll panels of 30∼80° and ±15°, respectively, providing efficient visualization of the uterus. These features make this robot a valuable addition to the surgical instruments available to gynecologic surgeons.

Restoration of Pulmonary Compliance after Laparoscopic Gynecologic Surgery Using a Recruitment Maneuver.

This study aimed to investigate the hypothesis that an alveolar recruitment maneuver can restore lung compliance to initial values after laparoscopic gynecological surgery. A total of 31 patients who underwent laparoscopic gynecological surgery were enrolled. Protective mechanical ventilation was applied, and the radial artery was catheterized in all patients. An alveolar recruitment maneuver (incremental and decremental positive end-expiratory pressure) was applied ten minutes after the release of pneumoperitoneum. The respiratory mechanics and blood gas results were recorded at eight different time points: after induction of anesthesia (T1), in the lithotomy position (T2), in the Trendelenburg position (T3), 10 and 90 min after insufflation of carbon dioxide (T4 and T5), in the supine position (T6), after desufflation (T7), and 10 min after an alveolar recruitment maneuver at the end of surgery (T8). Pneumoperitoneum and the Trendelenburg position caused a decline of 15 units in compliance (T7 vs. T1; p < 0.05) compared to baseline. After the alveolar recruitment maneuver, compliance increased by 17.5% compared with the mean value of compliance at time T1 (T8 vs. T1; p < 0.05). The recruitment maneuver had favorable results in patients with low initial compliance (41.5 mL/cmH2O, IQR: 9.75 mL/cmH2O), high Body Mass Index 30.32 kg/m2 (IQR: 1.05 kg/m2), and high initial plateau airway pressure (16.5 cmH2O, IQR: 0.75 cmH2O). Lung compliance does not return to initial values after performing laparoscopic gynecological procedures. However, after the release of pneumoperitoneum, an alveolar recruitment maneuver is beneficial as it improves compliance and gas exchange.

A web-based dynamic predictive model for postoperative nausea and vomiting in patient receiving gynecological laparoscopic surgery.

The aim of this study was to develop a web-based dynamic prediction model for postoperative nausea and vomiting (PONV) in patients undergoing gynecologic laparoscopic surgery. The patients (N = 647) undergoing gynecologic laparoscopic surgery were included in this observational study. The candidate risk-factors related to PONV were included through literature search. Lasso regression was utilized to screen candidate risk-factors, and the variables with statistical significance were selected in multivariable logistic model building. The web-based dynamic Nomogram was used for model exhibition. Accuracy and validity of the experimental model (EM) were evaluated by generating receiver operating characteristic (ROC) curves and calibration curves. Hosmer-Lemeshow test was used to evaluate the goodness of fit of the model. Decision curve analysis (DCA) was used to evaluate the clinical practicability of the risk prediction model. Ultimately, a total of five predictors including patient-controlled analgesia (odds ratio [OR], 4.78; 95% confidence interval [CI], 1.98-12.44), motion sickness (OR, 4.80; 95% CI, 2.71-8.65), variation of blood pressure (OR, 4.30; 95% CI, 2.41-7.91), pregnancy vomiting history (OR, 2.21; 95% CI, 1.44-3.43), and pain response (OR, 1.64; 95% CI, 1.48-1.83) were selected in model building. Assessment of the model indicates the discriminating power of EM was adequate (ROC-areas under the curve, 93.0%; 95% CI, 90.7%-95.3%). EM showed better accuracy and goodness of fit based on the results of the calibration curve. The DCA curve of EM showed favorable clinical benefits. This dynamic prediction model can determine the PONV risk in patients undergoing gynecologic laparoscopic surgery.

Objective assessment tools in laparoscopic or robotic-assisted gynecological surgery: A systematic review.

There is a growing emphasis on proficiency-based progression within surgical training. To enable this, clearly defined metrics for those newly acquired surgical skills are needed. These can be formulated in objective assessment tools. The aim of the present study was to systematically review the literature reporting on available tools for objective assessment of minimally invasive gynecological surgery (simulated) performance and evaluate their reliability and validity. A systematic search (1989-2022) was conducted in MEDLINE, Embase, PubMed, Web of Science in accordance with PRISMA. The trial was registered with the Prospective Register of Systematic Reviews (PROSPERO) ID: CRD42022376552. Randomized controlled trials, prospective comparative studies, prospective single-group (with pre- and post-training assessment) or consensus studies that reported on the development, validation or usage of assessment tools of surgical performance in minimally invasive gynecological surgery, were included. Three independent assessors assessed study setting and validity evidence according to a contemporary framework of validity, which was adapted from Messick's validity framework. Methodological quality of included studies was assessed using the modified medical education research study quality instrument (MERSQI) checklist. Heterogeneity in data reporting on types of tools, data collection, study design, definition of expertise (novice vs. experts) and statistical values prevented a meaningful meta-analysis. A total of 19 746 titles and abstracts were screened of which 72 articles met the inclusion criteria. A total of 37 different assessment tools were identified of which 13 represented manual global assessment tools, 13 manual procedure-specific assessment tools and 11 automated performance metrices. Only two tools showed substantive evidence of validity. Reliability and validity per tool were provided. No assessment tools showed direct correlation between tool scores and patient related outcomes. Existing objective assessment tools lack evidence on predicting patient outcomes and suffer from limitations in transferability outside of the research environment, particularly for automated performance metrics. Future research should prioritize filling these gaps while integrating advanced technologies like kinematic data and AI for robust, objective surgical skill assessment within gynecological advanced surgical training programs.

Effects of Bacillus coagulans TBC169 on gut microbiota and metabolites in gynecological laparoscopy patients.

The primary objective of this study is to investigate the mechanism by which Bacillus coagulans TBC169 accelerates intestinal function recovery in patients who have undergone gynecological laparoscopic surgery, using metabolomics and gut microbiota analysis. A total of 20 subjects were selected and randomly divided into two groups: the intervention group (n = 10) receiving Bacillus coagulans TBC169 Tablets (6 pills, 1.05 × 108 CFU), and the control group (n = 10) receiving placebos (6 pills). After the initial postoperative defecation, fecal samples were collected from each subject to analyze their gut microbiota and metabolic profiles by high-throughput 16S rRNA gene sequencing analysis and untargeted metabonomic. There were no statistically significant differences observed in the α-diversity and β-diversity between the two groups; however, in the intervention group, there was a significant reduction in the relative abundance of unclassified_Enterobacteriaceae at the genus level. Furthermore, the control group showed increased levels of Holdemanella and Enterobacter, whereas the intervention group exhibited elevated levels of Intestinimonas. And administration of Bacillus coagulans TBC169 led to variations in 2 metabolic pathways: D-glutamine and D-glutamate metabolism, and arginine biosynthesis. This study demonstrated that consuming Bacillus coagulans TBC169 after gynecological laparoscopic surgery might inhibit the proliferation of harmful Enterobacteriaceae; mainly influence 2 pathways including D-glutamine and D-glutamate metabolism, and arginine biosynthesis; and regulate metabolites related to immunity and intestinal motility; which can help regulate immune function, maintain intestinal balance, promote intestinal peristalsis, and thus accelerate the recovery of intestinal function.

Bupivacaine Local Infiltration at Trocar Insertion Sites after Gynecologic Laparoscopic Surgery: A Randomized, Double-blind, Placebo-Controlled Trial

Objective: To compare local infiltration of bupivacaine with placebo for reducing pain at trocar insertion sites after gynecologic laparoscopic surgery (GLS). Materials and Methods: A prospective, randomized, double-blind, placebo-controlled trial was conducted on women who underwent GLS at Buddhachinaraj Phitsanulok Hospital, Thailand between September 2021 and March 2022. Eighty subjects were included for this trial. Bupivacaine 0.5% 10-mL was infiltrated at each port site after removing the trocars compared with placebo. Pain intensity was evaluated by visual analog scale (VAS) for four pain points including abdominal parietal pain (APP), abdominal visceral pain (AVP), and right and left shoulder pain at 2, 4, 8, 12, and 24 hours postoperatively. Results: There were no significant differences in baseline characteristics between the two groups except for parity. APP and AVP had no significant difference in postoperative pain (mean difference –0.23, 95% CI –0.58 to 0.10, p=0.169 and –0.35, 95% CI -0.72 to 0.02, p=0.063, respectively). Only mild pain, with a VAS of 0 to 2, on both sides of shoulder were found in most participants, which had no significant difference between the two groups. Opioid consumption and adverse events were also not a significant difference. Multivariate analysis showed the APP had no significant difference between the two groups after adjusting confounding factors. However, gynecologic cancer and increased age were the significant factors associated with postoperative pain (mean difference 0.60, 95% CI 0.12 to 1.08, p=0.014 and –0.02, 95% CI –0.04 to –0.01, p=0.010, respectively). Conclusion: Locally infiltrated bupivacaine at trocar insertion sites after GLS did not significantly improve postoperative analgesia.

Robot Assisted Laparoscopic Surgery in Gynaecology: An Evolving Assistive Technology.

Laparoscopic surgery is extensively utilized to treat a range of gynaecological conditions and pathologies. The advantages of laparoscopic surgery include the minimalization of blood loss and scarring, improved recovery times, and shorter hospital admissions. However, robotic technologies have had an increasing presence within gynaecological laparoscopic surgery in recent decades. This literature review therefore aims to discuss laparoscopy from 3 perspectives. First, the evolution of laparoscopy is reviewed with a focus on its origins, its transition from a diagnostic to an operative tool, and its role in present-day gynaecology. Second, interventions for benign gynaecological conditions (including excision of benign ovarian tumours, total laparoscopic hysterectomy, and laparoscopic myomectomy) are reviewed. The laparoscopic management of malignant gynaecology (including ovarian cancer, endometrial cancer, and cervical cancer) is also discussed. Finally, whilst robot-assisted laparoscopic surgery is experiencing rapid technological advancement, it is pertinent to consider the extent of its benefits when compared to open or conventional laparoscopic approaches in gynaecological surgery.

Penehyclidine for Prevention of Postoperative Nausea and Vomiting in Patients Undergoing Gynecological Laparoscopic Surgery Under Combined Intravenous and Inhalation Anesthesia: A Randomized, Double-Blind, Placebo-Controlled Trial.

We designed this study to investigate the effect of intravenous use of penehyclidine on postoperative nausea and vomiting (PONV) after gynecological laparoscopic surgery. Ninety-two Women Patients (Aged ≥ 18) Scheduled for Elective Gynecologic Laparoscopy Were Enrolled in the Current Study. Patients Were Equally Randomized Assigned Into Penehyclidine group (PHC group: received a bolus of penehyclidine 10 μg/kg during the induction of anesthesia, then followed by a continuous infusion of 10 μg/kg penehyclidine at a fixed rate of 2.0 mL/h in postoperative intravenous analgesia pump over 48h, 0.5 mg upper limit respectively) or Control group (received 0.9% saline in replace of penehyclidine at the same time points). The primary outcome measure was the incidence of postoperative nausea and vomiting in the postanesthesia care unit and ward area. Quality of Recovery-15 (QoR-15) scores and general comfort questionnaire (GCQ) scores were assessed on postoperative day (POD) 1, 2. Patients between two groups had comparable baseline characteristics. Compared with the Control group, the incidence and severity of PONV, postoperative nausea (PON), and postoperative vomiting (POV) were significantly lower in the PHC group at 2h (PONV: P = 0.002, P = 0.004, respectively; PON: P = 0.018, P = 0.038, respectively; POV: P = 0.011, P = 0.072, respectively), 24h (PONV: P = 0.003, P = 0.001, respectively; PON: P = 0.010, P = 0.032, respectively; POV: P = 0.006, P = 0.044, respectively), and 48h (PONV: P = 0.003, P = 0.002, respectively; PON: P = 0.007, P = 0.019, respectively; POV: P = 0.002, P = 0.013, respectively) after surgery. The QoR-15 and GCQ scores of the PHC group were significantly higher than those of the Control group at POD 1, 2 (P < 0.001; P < 0.001, respectively). Our findings suggest that perioperative intravenous application of penehyclidine can effectively prevent postoperative nausea and vomiting in gynecological laparoscopic surgery patients and improve postoperative recovery.

Advantages of laparoscopy in gynecologic surgery in elderly patients.

Geriatric patients requiring gynecological surgery is increasing worldwide. However, older patients are at higher risk of postoperative morbidity and mortality, particularly cardiopulmonary complications. Laparoscopic surgery is widely used as a minimally invasive method for reducing postoperative morbidities. We compared the outcomes of open and laparoscopic gynecologic surgeries in patients older than 55 years. We included patients aged >55 years who underwent gynecological surgery at a single tertiary center between 2010 and 2020, excluding vaginal or ovarian cancer surgeries were excluded. Surgical outcomes were compared between the open surgery and laparoscopic groups, with age cutoff was set at 65 years for optimal discriminative power. We performed linear or logistic regression analyses to compare the surgical outcomes according to age and operation type. Among 2,983 patients, 28.6% underwent open surgery and 71.4% underwent laparoscopic surgery. Perioperative outcomes of laparoscopic surgery were better than those of open surgery in all groups. In both the open and laparoscopic surgery groups, the older patients showed worse overall surgical outcomes. However, age-related differences in perioperative outcomes were less severe in the laparoscopic group. In the linear regression analysis, the differences in estimated blood loss, transfusion, and hospital stay between the age groups were smaller in the laparoscopy group. Similar restuls were observed in cancer-only and benign-only cohorts. Although the surgical outcomes were worse in the older patients, the difference between age groups was smaller for laparoscopic surgery. Laparoscopic surgery offers more advantages and safety in patients aged >65 years.

Comparative analysis of low versus normal pressure pneumoperitoneum in laparoscopic gynecological surgeries: a randomized control trial

Comparative analysis of low versus normal pressure pneumoperitoneum in laparoscopic gynecological surgeries: a randomized control trial

Efficacy and feasibility of the RADA16 self-assembling peptide, PuraStat® for haemostasis in laparoscopic gynaecological surgery: A pilot study.

Bleeding after laparoscopic gynaecological surgery remains a potential complication. We assessed RADA16 (PuraStat®), a topical self-assembling peptide haemostatic agent, in a pilot study of 46 women undergoing laparoscopic gynaecological surgery. The primary outcome was intraoperative haemostatic efficacy for resection site bleeding. Haemostasis was achieved in all intraoperative bleeding situations (40/40 participants: 100%) with no clinically significant surgical bed bleeding or complications. Mean volume and time required to achieve haemostasis were 6 mL and 14 sec, respectively. This study suggests that PuraStat® is a safe, effective haemostatic agent in laparoscopic gynaecological surgery. Randomised controlled trials are warranted to confirm these findings.

Dexmedetomidine nasal administration improves perioperative sleep quality and neurocognitive deficits in elderly patients undergoing general anesthesia

ObjectiveTo investigate the improvement of perioperative sleep quality and neurocognitive impairment in elderly patients under general anesthesia by nasal administration of dexmedetomidine.MethodsOne hundred and twenty patients admitted to our hospital for various laparoscopic elective gynecological surgeries lasting more than 1 h under general anesthesia from July 2021 to March 2023 were selected. All subjects were divided into 3 groups according to the random number table method. From 21:00 to 21:30 every night from one day before to 5 days after surgery, group A was given alprazolam 0.4 mg orally; group B was given dexmedetomidine 1.5ug/kg nasal drip; group C was given saline nasal drip. All subjects were observed for general information, sleep quality, postoperative cognitive function, anxiety status, sleep quality, adverse effects and complication occurrence.ResultsThe difference in general information between the three groups was not statistically significant, P > 0.05; the sleep quality scores of the three groups on admission were not statistically significant, P > 0.05. At the Preoperative 1d, postoperative 1d, 3d and 5d, the RCSQ scores of the subjects in group A and group B were higher than those in groups C, and with the postoperative RCSQ scores of subjects in group B were higher as the time increased; the assessment of anxiety status in the three groups 1d before surgery was not statistically significant, P > 0.05. The cognitive function scores of subjects in the three groups were not statistically significant in the preoperative 1d, P > 0.05. The postoperative 1d (24.63 ± 2.23), 3d (25.83 ± 2.53), and 5d (26.15 ± 2.01) scores of the subjects in group B were higher than those in groups A and C (P < 0.05), and the subjects in group B had better recovery of postoperative cognitive function with increasing time; the occurrence of postoperative delirium (POD) in group B (12.5%) were lower on postoperative 5d than those in groups A (37.5%) and C (32.5%) (P < 0.05). There was no statistical significance in the evaluation of anxiety state of the three groups on the first day before operation (P > 0.05). The scores in group B were lower than those in group C on the postoperative 1d, 3d, 5 d (P < 0.05). The overall incidence of adverse reactions and complications in subjects in group B was 17.5% significantly lower than that in groups A and C (P < 0.05).ConclusionDexmedetomidine can effectively improve the sleep disorder of elderly general anesthesia patients, reduce the damage to their neurocognitive function and the occurrence of POD, effectively reduce the anxiety of patients and the occurrence of adverse reactions and complications, and has better sedative, improve postoperative cognitive function and anti-anxiety effects, with a high drug safety, worthy of clinical application and promotion.

Infectious Complications in Laparoscopic Gynecologic Oncology Surgery within an ERAS-Compliant Setting.

Minimally Invasive Surgery (MIS) represents a safe and feasible option for the surgical treatment of gynecologic malignancies, offering benefits, including reduced blood loss, lower complications, and faster recovery, without compromising oncological outcomes in selected patients. MIS is widely accepted in early-stage gynecologic malignancies, including endometrial cancer, cervical tumors measuring 2 cm or less, and early-stage ovarian cancer, considering the risk of surgical spillage. Despite its advantages, MIS does not rule out the possibility of adverse events such as postoperative infections. This retrospective study on 260 patients undergoing laparoscopic surgery at Parma University Hospital for gynecologic malignancies explores the incidence and risk factors of postoperative infectious complications. The Clavien-Dindo classification was used to rank postoperative surgical complications occurring 30 days after surgery and Enhanced Recovery After Surgery (ERAS) recommendations put into practice. In our population, 15 (5.8%) patients developed infectious complications, predominantly urinary tract infections (9, 3.5%). Longer surgical procedures were independently associated with higher postoperative infection risk (p = 0.045). Furthermore, C1 radical hysterectomy correlated significantly with infectious complications (p = 0.001, OR 3.977, 95% CI 1.370-11.544). In conclusion, compared to prior research, our study reported a lower rate of infectious complications occurrence and highlights the importance of adopting infection prevention measures.
