Filter by:The purpose of this trial is to compare the effect of different fluid volume infusion on ocular parameters in patients undergoing spine surgery in prone position.
Colonoscopy is one of the most common endoscopic procedures today. However, it sometimes can be a serious challenging situation both for the clinicians and patients. In this study, the investigators tried to determine which colonoscopic position allows easy, fast and comfortable way.
compare the prone with the prone-flexed position accessibility of upper and middle calyceal approach by subcostal puncture and PCNL reporting complications using the Clavien-Dindo system with Categorisation of PCNL-specific complications according to Clavien-Dindo classification score
The changes in the cuff pressure in the absence of nitrous oxide are less clear.In the current study, we aim to determine the changes in cuff pressure over time in infants undergoing myelomeningocele repair in prone position under general anesthesia in the absence of N2O.
Beneficial effect of prone position in ARDS on mortality is not linked to increase in PF ratio. It is probably due to improvement in ventilation-perfusion ratio (V/Q). Volumetric capnography allows assessment of dead space and homogeneity of V/Q. All prone positionned patients will be included in the study with usual monitoring (i.e. respiratory system basic mechanics, volumetric capnography, blood gas samples). Epidemiologic and monitoring data will be collected during all prone position sessions.
NICOM® is a recently developed noninvasive cardiac output monitoring device, and indices derived from NICOM® such as SVV has been reported to predict fluid responsiveness in the previous studies. However, its usefulness in prone positioning has not been investigated. Thus, the aim of this prospective observational study is to evaluate the usefulness of stroke volume variation (SVV) derived from NICOM® to predict fluid responsiveness in prone patients undergoing spine surgery.
Spine surgery is the most common procedure in neurosurgical setting. Some centers have chosen the patient self-position to avoid complications such as accidental extubation or loss of the iv line. The aim of our retrospective study is to describe our experience in the laryngeal mask use for airway management in patient submitted to spine surgery in neurosurgery
Increased intra-abdominal pressure(IAP) might influence on perioperative morbidity related to increased CVP, PVWP, SVR, PAP and decreased venous return and cardiac output. Prone position has been known to increase IAP. In clinical field, various apparatuses has developed to minimize IAP elevation during prone position operation. In this study, we would compare the changes of IAP and respiratory system compliance according to positional apparatus in prone position.
Recent occurrence of significant post-operative liver impairment at Nottingham University Hospitals NHS Trust has prompted investigation into whether interaction between general anaesthesia and prone positioning (lying face down) for surgery can influence liver function. Historical research has shown that the heart does not function as efficiently when an anaesthetised patient is placed in the prone position for surgery. The techniques used for anaesthetising and monitoring these patients have changed remarkably, since these studies were first performed. It is important to know accurately how the heart functions to enable better understanding of the changes in blood flow to the liver when in the prone position. Studies looking at blood flow to the liver when lying face down have been done before but are mainly reporting patients on the intensive care unit. These intensive care patients are different to those in theatre undergoing routine surgery. The intensive care patients are usually received in different types of drugs and monitored with several different types of monitor at the time. Perhaps most importantly is that they are placed face down on a soft air cushioned mattress and pillows rather than the rigid support used for surgical patients. This study will look at whether the function of the liver changes when a patient is anaesthetised and is then rolled onto their front. The function of the liver will be measured by looking how it clears a specific drug from the blood. Also this study will look at how accurate a particular type of heart monitor is when an anaesthetised patient is placed onto their front.
