Filter by:Cesarean section is one of the most common major surgical operations among women. In 2015, the incidence of cesarean section in Woman Health Hospital in Assiut University accounts for 51.3 % of all deliveries
The patients were recruited from women attending labor ward to undergo cesarean section.
The aim of this study is to determine the validity of Kleinhauer Betke in women with known hemoglobinopathy for fetal-maternal hemorrhage.
This study will evaluate if clazosentan (on top of normal routine medical care) can reduce the risk of developing complications related to cerebral vasospasm and permanent brain damage as compared to normal routine medical care alone.
Upper gastrointestinal (UGI) bleed of variceal origin is a common medical emergency. Prompt endoscopic variceal ligation (EVL) is therapeutic as well as diagnostic. Terlipressin, a vasopressin analog (intravenous, 2 mg q 4 hourly), is widely used promptly in any suspicious case of variceal haemorrhage (VH) before endoscopic procedure, along with volume and blood resuscitative measures. As per guideline, after EVL Terlipressin therapy (1 mg IV q 4 hourly) is continued for 2-5 day to prevent re-bleed. But the prolong use of Terlipressin is not completely safe as well as it is expensive also in resource constraint setting. At present there is no clinical trial available to prove the efficacy of post-EVL Terlipressin therapy in preventing re-bleed and mortality in cases of acute variceal haemorrhage. During the post marketing surveillance Terlipressin therapy has been found to be associated with life threatening complication like cardiac arrhythmia, myocardial ischemia, critical vasoconstriction of peripheral as well as internal organ leading to ischemia or gangrene, severe hyponatremia, hypertension, fluid overload and pulmonary oedema. So the justification of continuing Terlipressin therapy for 5 days after EVL is questionable, as haemostasis is primarily achieved by EVL and the risk versus benefit of Terlipressin therapy after EVL is still unknown. Continue IV Terlipressin therapy also prolongs in-hospital care causing further increase of health care burden. There is still lack of data of Terlipressin therapy, regarding its efficacy in preventing post-EVL re-bleed, mortality, adverse drug events and cost effectiveness. The investigator will study to evaluate the utility of Terlipressin therapy after EVL, in acute variceal haemorrhage.
The cesarean section is a bloody operation, about 750 to 1000 ml are lost at most operations and over 1000 ml of blood have lost to bring them into the definition of a postpartum hemorrhage (PPH). In developing countries, PPH is the main cause of maternal deaths. Uterine atony is the most common cause of immediate heavy PPH.Multiple pregnancy ones of a common factor for uterine atony. The administration of oxytocic's after the delivery of the neonate reduces the likelihood of PPH and 5 IU oxytocin by slow intravenous injection is currently recommended for all cesarean sections. However, the use of additional oxytocic medication is common, to arrest bleeding, or prophylactically if there are risk factors for PPH . Carbetocin is a synthetic analog of human oxytocin with structural modifications that increase its half-life, thereby prolonging its pharmacological effects. Carbetocin has been approved in 23 countries for prevention of uterine atony and excessive bleeding following cesarean delivery in spinal or epidural anesthesia. Oxytocin is a peptide of nine amino acids (Nona peptide). The structure of oxytocin is very similar to that of arginine vasopressin, whose sequence differs from oxytocin by 2 amino acids. The best-known mechanism for oxytocin to exert its stimulatory effect on myometrial contractility is by increasing the intracellular concentration of calcium. Owing to its short plasma half-life (mean 3 min), a continuous intravenous infusion is required to maintain the uterus in a contracted state. The usual dose is 20 IU in 500 ml of crystalloid solution, with the dosage rate adjusted according to response. Ergometrine is a selective and moderately potent tryptaminergic receptor antagonist in various smooth muscles, being only a partially agonistic or antagonistic at tryptaminergic receptors in the central nervous system. In blood vessels, the alkaloid is only weakly antagonistic of dopaminergic receptors and partially agonistic of α-adrenergic receptors. oxytocin (19%). Blood loss>500 ml was only observed in women who received oxytocin. The aim of the investigator's study was to compare the effect of carbetocin vs. oxytocin and ergometrine for prevention of PPH during cesarean section in women with multiple pregnancies.
Novel technology enables it to monitor noninvasively the vital signs of a patient. Such a monitoring is immediately required to improve patient safety and to reduce hospital readmissions. In this study, novel bed- and wearable sensors are studied for this purpose.
The present study aims to look at the effect of terlipressin infusion on blood loss and blood transfusion needs during Whipple procedure
Objective: To investigate the effect of A glove-loaded Foley's catheter tamponade versus stepwise uterine devascularization on blood loss during cesarean section (CS) in patients with complete placenta previa.
Published trials on tranexamic acid (TxA) for prevention have used a variety of fixed (0.5gm or 1gm) and body-weight adjusted (10mg/kg or 15mg/kg) doses of TxA. Given the wide range of bodyweights of pregnant women in contemporary obstetric practice, it is critical to determine the minimum effective dose of TxA, so as to avoid under- or over-dosing. The rationale of this study is to determine the minimum effective dose of TxA that is required to attain therapeutic plasma levels of TxA, established at 5-15mg/L, following administration of a single dose of intravenous (IV) TxA after childbirth and the clamping the umbilical cord, and before delivery of the placenta. Following birth of the infant, and upon clamping the umbilical cord, the investigators will administer a single dose of IV TxA in 100ml of 0.9% sodium chloride at 50mg/min according to the dose-escalation schedule described below. The slow rate of infusion has been chosen to prevent untoward effects such as hypotension that have been noted when the rate of infusion has exceeded 100mg/min. As part of the dose-escalation design, the investigators will start with 5mg/kg, half the smallest described dose, on a sample of up to 5 women. They will continue to administer TxA doses in increments of 5mg/kg to each successive batch of 5 women. If the number of treatment successes cannot statistically rule out a value < 75% (< 4 of 5 women are successes due to values in the low range), the dose will be increased by 5mg/kg for the next set of 5 women, and so on, until a maximum dose of 30mg/kg is reached, a dose deemed safe based on earlier studies in different populations. Once treatment success is determined at a certain dose, i.e. 4/5 women have levels in the therapeutic range), a total of 20 women will be administered that dose to ensure that 75% i.e. 18/20 women are successes at that dose.
