Filter by:BACKGROUND: The steep Trendelenburg position and pneumoperitoneum are used to improve surgical visibility in robot-assisted laparoscopic radical prostatectomy (RALRP). However, these procedures can lead to hemodynamic changes. This study aimed to investigate the effects of these interventions on the perfusion index (PI) and the Pleth variability index (PVI) in patients undergoing RALRP under general anesthesia. METHODS: Fifty-three patients scheduled for RALRP underwent standard monitoring; PI and PVI values were monitored using a finger probe. PI, PVI, hemodynamic and respiratory parameters, and intraabdominal pressure were recorded before and after anesthesia induction, after adopting the Trendelenburg position, after pneumoperitoneum, after pneumoperitoneum and the Trendelenburg position, at 15 min, 30 min, in the supine position, after carbon dioxide (CO2) desufflation, and after extubation.
Laparoscopic bariatric surgery are becoming the most used procedure to treat the obesity. To facilitate safe initial access to the abdominal cavity, we insert an optical viewing trocar at the left hypocondrium. The aim of this study is to systematically evaluate all published data existing in the literature to analyze the safety of optical trocars in patients undergoing bariatric surgery and to compare these data with our experiences.
Previous studies conducted on the hemodynamic effects of pneumoperitoneum pressures created by different insufflation flows are very limited in the literature. In a current literature review, there was no study found comparing the effects of hemodynamic changes created by low and high insufflation flows and pneumoperitoneum pressure on cerebral oxygenation. The purpose of the study was to contribute to the literature by investigating the effects of pneumoperitoneum pressures created by different flows on brain oxygenation.
The investigators hypothesized that deep neuromuscular block compare to moderate neuromuscular block would reduce the rate of increasing intraabdominal pressure and operation can be completely done in lower pressure pneumoperitoneum and would improve laparoscopic space by measuring distance from the sacral promontory to the inserted trocar in patients undergoing laparoscopic gynaecological surgery.
18 participants (novices, intermediates and experts) performed in total 248 insertions in a systematic way on Thiel embalmed bodies with wide and small bore versions of the conventional VNc (conventional Veress Needle) and the VN+(The Veress Needle plus). Insertion depth was measured by recording the graduations on the needle under direct laparoscopic vision.
In our study, to show the effect of pneumoperitoneum on acute kidney injury in patients scheduled for laparoscopic surgery, NGAL and IGF-1 values will be measured before, after and 24 hours after pneumoperitoneum, and these values will be compared. In our study, we aimed to investigate the effect of pneumoperitoneum applied on acute kidney injury in patients who underwent laparoscopic surgery. Creatinine and NGAL have been used successfully in the follow-up of acute kidney injury. Our study investigates whether IGF-1 will be an effective indicator in acute kidney injury by comparing IGF-1 and NGAL values before pneumoperitoneum, after pneumoperitoneum and at the postoperative 24th hour.
The purpose of this study is to assess the effect of low-pressure pneumoperitoneum on post operative pain and inflammation in patients undergoing elective laparoscopic cholecystectomy by comparing it to standard practice.
Clinic and metabolic consequences of pneumoperitoneum, achieved by insufflation of gas carbon dioxide, are still debated. Cardiovascular system suffering due to the compression of intra-abdominal venous structures can cause life-threatening complications. Increased partial pressure of carbon dioxide induces metabolic acidosis with further vascular suffering. Pneumoperitoneum reduces the pulmonary exchange volumes and bring renal suffering. Methods. The aim of this study is to evaluate the alterations in hemodynamic and hemogasanalysis parameters during the laparoscopic surgery at different pressure settings of pneumoperitoneum in order to assess the best pressure value. We evaluated and compared intraoperative hemodynamic and hemogasanalytic alterations in two groups of patients respectively subdue to laparoscopic cholecystectomy at a pneumoperitoneum pressure of 12 mmHg (group A) and at a pressure of 8 mmHg (group B).
Intravenous lidocaine - a potent local anesthetic with analgesic and anti- inflammatory properties has been shown to be an effective adjunct that reduces intra and postoperative opioid consumption and facilitates pain management in adults. In children population promising but limited evidence is available. The study has been planned to evaluate the efficacy of continuous intravenous infusion of lidocaine in alleviation of hemodynamic reaction to tracheal intubation, as well as metabolic and hormonal response to laparoscopic procedure in children.
Trendelenburg position and carbon dioxide (CO2) pneumoperitoneum are in association with increased intracranial pressure (ICP) reflected by the optic nerve sheath diameter (ONSD). Measurement of ONSD by ultrasound (US) guidance can be used in the diagnosis of ICP. The investigators interrogated the effects of lateral 45° downward position and CO2 insufflation on ONSD in patients undergoing laparoscopic transperitoneal nephrectomy.
