Accuracy of Blood Loss Measurement during Cesarean Delivery
Objective This study aims to compare the accuracy of visual, quantitative gravimetric, and colorimetric methods used to determine blood loss during cesarean delivery procedures employing a hemoglobin extraction assay as the reference standard. Study Design In 50 patients having cesarean deliveries blood loss determined by assays of hemoglobin content on surgical sponges and in suction canisters...
متن کاملReliability of Visually Estimated Blood Loss with Hemoglobin Measurement: 200 Cases of Craniosynostosis Surgery
Background Bleeding is one of the most common complications of craniosynostosis surgery, which its appropriate management is associated with better post-operative outcomes. The aim of this retrospective study was to evaluate the visual estimated blood loss in intraoperative management of infants with craniosynostosis surgery. Materials and Methods This retrospective study was performed on 200 p...
متن کاملBlood loss during prostatectomy.
PROSTATECTOMY is an operation in which all surgeons, however skilled, sometimes have difficulty in controlling haemorrhage. As the operation is usually done in elderly men who cannot withstand severe haemorrhage, it is important to estimate the blood loss and to replace it; alternatively the anaesthetist can take steps to diminish the bleeding by lowering the blood pressure. Figures for the mea...
متن کاملAn Assessment of Pulse Transit Time For Detecting Heavy Blood Loss During Surgical Operation
The main contribution of this paper is the use of non-invasive measurements such as electrocardiogram (ECG) and photoplethysmographic (PPG) pulse oximetry waveforms to develop a new physiological signal analysis technique for detecting blood loss during surgical operation. Urological surgery cases were considered as the control group due to its generality, and cardiac surgery as experimental gr...
متن کاملReservoir Operation During Droughts
Drought is an inevitable part of the world’s climate. It occurs in wet as well as in dry regions. Therefore, planning for drought and mitigating its impacts is essential. In this study, a hedging rule is developed using the zero/one mixed integer-programming approach. Furthermore, some procedures are introduced to ease the computational burden inherent in integer programming. Hedging rules are ...
