Filter by:The main objective is to investigate whether listening to recorded music has a positive effect on the execution of laparoscopic skills. Secondary objectives are to investigate the effects of music during surgical performance on blood pressure, mental workload and heart rate. Study design: This will be a 4-period 4-sequence 2-treatment crossover study, participants will be exposed to both control (noise cancelling headphones without music) and the intervention (preferred music via headphones) whilst performing a laparoscopic task in a box trainer. Every period consists of 5 repetitions of a laparoscopic peg transfer task. In total participants will perform in each condition 10 peg transfer tasks. Prior to the experiment, all participants practice the laparoscopic peg transfer task 20 times Study population: Healthy volunteering medicine students without laparoscopic experience. Intervention (if applicable): Participants will perform 2 periods of 5 laparoscopic peg transfer task whilst listening to preferred recorded music via headphones and 2 periods of 5 laparoscopic peg transfer tasks while wearing noise cancelling headphones without music (2 periods of 5 tasks). Main study parameters/endpoints: The primary endpoint is laparoscopic performance as defined by time of task completion Secondary endpoints are: laparoscopic task performance (path length, jerk, error score, economy of motion) vital parameters (heart rate, and post test blood pressure) and mental workload (SURG-TLX)
This project will study the effect of oxytocin on hemodynamics in patients undergoing laparoscopic myomectomy, and how to prevent and manage such hemodynamic changes effectively.It provides a reference for the rational use of oxytocin in clinical practice, which can not only effectively contract the uterus and reduce bleeding, but also reduce the influence on hemodynamics.
In this randomized control trial the patients with acute appendicitis will be divided in three groups according to the management of the appendiceal stump(Endostapler, Endoloop or Endoclip). Pre-, peri- and postoperative data will be analysed.
Laparoscopic surgery can induce hemodynamic pertubations. Pneumoperitoneum, inevitable in laparoscopic surgery, induces increase in intra-abdominal pressure, which can decrease cardiac output. Simultaneously, pneumoperitoneum can stimulate sympathetic system and increase vascular resistance/arterial blood pressure. Patients undergoing laparoscopic surgery may show a normal range of blood pressure during pneumoperitoneum even when the patients are in hypovolemia, and desufflation at the end of main surgical procedure can cause an abrupt hypotension revealing hypovolemia. Therefore, appropriate fluid management is essential for preventing desufflation-induced hypotension in laparoscopic surgery. Recently, dynamic variables are used to predict and guide fluid therapy during controlled ventilation. these variables arise from heart-lung interactions during positive ventilation, which influence left ventricular stroke volume. Several dynamic variables are derived from variations in left ventricular stroke volume (stroke volume variation, SVV), for example pulse pressure variation (PPV), and variations in pulse oximetry plethysmography waveform amplitude (PWV), which have all been shown to predict fluid responsiveness in different clinical and experimental settings. However, there are few evidences regarding which type of dynamic variables can predict desufflation-induced hypotension in laparoscopic surgery. Therefore, this study was designed to assess the predictive abilities of three different type of dynamic variables including PPV, SVV, and PWV for desufflation-induced hypotension in patients undergoing laparoscopic surgery.
Peritoneal perfusion during laparoscopic surgery is quantified by video recording after intravenous injection of indocyanine green at a pneumoperitoneum pressure of 8, 12 and 16 mmHg.
The purpose of this study is to explore the safety and feasibility of laparoscopic spleen-preserving No. 10 lymph node dissection for patients with advanced middle or upper third gastric cancer.
To determine the effect of post-operative abdominal binder usage on total narcotic usage after undergoing surgery. To determine if abdominal binder usage results in decreased visual analog scale (VAS) pain scores and shorter time to first ambulation post operatively.
To identify the best surface to minimize the risk of intra-operative slipping when placed in Trendelenburg position. The outcomes of interest are to minimize the amount of movement from predefined anatomic landmarks and maximize the ease of performing the intended surgery. The study consists of performing a randomized trial comparing 3 common anti-slip surfaces to determine which surface provides the best result in terms of safety and cost.
A randomised controlled trial (RCT) comparing the closed (Veress needle) with the open (Hasson) laparoscopic entry technique in haemodynamically stable patients undergoing either emergency or elective surgical procedures was conducted over a 13-month period. The success rate and complications related to the technique were recorded and analysed.
Laparoscopy is increasingly used for major abdominal and pelvic surgery. As this approach is also recommended in elderly patients with serious comorbidities, optimal fluid therapy guidance during this procedure is important. Many studies have reported that less invasive dynamic indices such as pulse pressure variation (PPV) and stroke volume variation (SVV), which are derived from the arterial pressure waveform, are superior to static indices to predict fluid responsiveness. PPV and SVV are based on the heart-lung interaction and reflect cyclic changes in stroke volume induced by mechanical ventilation in the closed-chest condition. Therefore, their ability to predict fluid responsiveness can be affected by factors that influence the arterial tone or the compliance of the respiratory system. Laparoscopic surgery for the abdominal visceral organs requires pneumoperitoneum and the Trendelenburg position to optimize surgical conditions, and can reduce cardiac output and respiratory compliance. Accordingly, the usefulness of PPV and SVV in predicting fluid responsiveness during laparoscopic surgery under these conditions may be questioned. It has been clearly shown that the values of dynamic parameters are significantly correlated with the magnitude of VT. Min et al. reported that augmentation of PPV and SVV via a temporary increase in VT from 8 to 12 ml/kg improved their predictive power in the inconclusive zone with respect to fluid responsiveness (PPV values of 9% and 13%, respectively). Another recent study reported that on increasing VT from 6 to 8 ml/kg, augmented PPV and SVV, as well as their absolute changes, predicted fluid responsiveness with high sensitivity and specificity, even in critically ill patients receiving low VT. Therefore, the aim of the current study was to investigate whether increasing VT from 6 to 8 ml/kg would improve the predictive power of PPV and SVV in patients undergoing robot-assisted laparoscopic surgery in the Trendelenburg position under lung-protective ventilation. We also assessed the ability of absolute changes in PPV and SVV values induced by a temporary increase in VT from 6 to 8 ml/kg to predict fluid responsiveness.
