1/5. Subarachnoid haemorrhage following spinal anaesthesia in an obstetric patient.We describe an obstetric patient who presented for removal of a retained placenta. After insertion of the spinal anaesthetic, she developed a severe headache, and a subarachnoid haemorrhage was diagnosed. We discuss the differential diagnosis of the headache, the occurrence of intracranial haemorrhages after dural puncture and the future management of this patient.- - - - - - - - - - ranking = 1keywords = haemorrhage (Clic here for more details about this article) |
2/5. Anti-shock garment provides resuscitation and haemostasis for obstetric haemorrhage.OBJECTIVE: To evaluate the feasibility, safety and effectiveness of the non-pneumatic anti-shock garment for resuscitation and haemostasis following obstetric haemorrhage resulting in severe shock. DESIGN: During a six-week period, the author served a locum tenens as the obstetrician consultant for the Memorial Christian Hospital, Sialkot, pakistan. All women who suffered from severe obstetric haemorrhage were managed with the anti-shock garment as the first intervention. The data for this report were collected from hospital chart review. SETTING: Sialkot is a city of about three million and Memorial Christian Hospital is one of two major obstetric hospitals. There is no blood bank at Memorial Christian Hospital or elsewhere in Sialkot. The Memorial Christian Hospital laboratory is able to draw donor blood, type and cross match blood, and process it for transfusion 24 hours per day. population: During the six weeks of this study, in June and July 2001, there were 764 deliveries and 34 other admissions within a week following deliveries outside the hospital. Seven women with obstetric haemorrhage who developed severe shock were managed with the anti-shock garment. One woman, who was later found to have mitral stenosis, developed dyspnea upon placement of the anti-shock garment and therefore it was removed within 5 minutes. This report concerns the six women who were able to tolerate the anti-shock garment without untoward symptoms. methods: As soon as severe shock was recognised in the hospital, the anti-shock garment was placed. Crystalloid solutions were given intravenously over the first hour at a rate of 1500 mL per estimated litre of blood loss, then at a maintenance rate of 150 mL/hour. vital signs every 15 to 30 minutes, hourly urine output and intermittent oxygen saturation were used to monitor patients during the use of the anti-shock garment. When sufficient blood transfusion had been given to restore the haemoglobin to >7 g/dL, the anti-shock garment was removed in segments at 15-minute intervals with documentation of vital signs before removal of each subsequent portion. MAIN OUTCOME MEASURES: Restoration of mean arterial pressure of 70 mmHg and clearing of sensorium were considered as signs of effective resuscitation. Haemorrhage was considered controlled if the blood loss was less than 25 mL/hour. morbidity included any complications noted in the medical chart. RESULTS: Restoration of blood pressure and improvement of mental status occurred within 5 minutes in two patients who were pulseless and three who were unconscious or confused. All patients had improvement of mean arterial pressure to greater than 70 mmHg within 5 minutes. Duration of anti-shock garment use ranged from 12 to 36 hours and none of the six women had significant further bleeding while the anti-shock garment was in place. patients were comfortable during use of the anti-shock garment and no adverse effects were noted apart from a transient decrease in urine output. CONCLUSIONS: The anti-shock garment rapidly restored vital signs in women with severe obstetric shock. There was no further haemorrhage during or after anti-shock garment use and the women experienced no subsequent morbidity. A prospective randomised study of the anti-shock garment for management of obstetric haemorrhage is needed to further document these observations.- - - - - - - - - - ranking = 1.5keywords = haemorrhage (Clic here for more details about this article) |
3/5. Intravenous nitro-glycerine versus general anaesthesia for placental extraction--a sequential comparison.BACKGROUND: Postpartum haemorrhage due to retained placenta is one of the commonest life-threatening conditions during the third stage of labour. Uterine relaxation is usually required to facilitate placental removal. 'Full-stomach' obstetric patients (which includes those who delivered within 48 h), parturients with a history of antepartum or recurrent postpartum hemorrhage, grand multiparity, twin pregnancy, and those with cardiac abnormalities may benefit from an alternative to volatile-based general anaesthesia for uterine relaxation to avoid complications associated with the technique (e.g. aspiration pneumonitis and cardiovascular compromise). CASE REPORT: A 34-year-old gravida 4, para 3 parturient with rheumatic valvular heart disease presented with retained placenta and postpartum haemorrhage on two consecutive deliveries and had the placenta removed manually by the same surgeon under two different anaesthetic techniques. On the first occasion, general anaesthesia was administered whereas only i.v. fentanyl and nitro-glycerine were used on the second occasion. The postoperative course was uneventful on both occasions. CONCLUSIONS: The use of nitro-glycerine was found to be efficacious for manual removal of placenta with minimal haemodynamic perturbations, avoiding the use (and associated risks) of general anaesthesia for uterine relaxation. The ability of nitro-glycerine to reduce spontaneous uterine activity, induce uterine relaxation, coupled with its short duration of action and high efficacy, may render it a safe alternative to general anaesthesia for facilitating intrauterine manoeuvres. Nitro-glycerine may be useful especially in patients with associated co-morbid chronic cardiac conditions, e.g. rheumatic heart disease, which is characterised by impaired haemodynamics and cardiac reserves.- - - - - - - - - - ranking = 0.33333333333333keywords = haemorrhage (Clic here for more details about this article) |
4/5. Term angular pregnancy with placenta accreta. A case report.A 27-year-old primigravida, with two prior adnexal operations, had retained placenta with postpartum haemorrhage following an uncomplicated vaginal delivery. Laparotomic removal revealed placental accretism. Pharmacological treatment (oxytocin and sulprostone) and right cornual resection failed to control profuse bleeding. In the end, subtotal hysterectomy was unavoidable.- - - - - - - - - - ranking = 0.16666666666667keywords = haemorrhage (Clic here for more details about this article) |
5/5. Management of a parturient with paroxysmal nocturnal haemoglobinuria.We present the case of a 30-year-old parturient diagnosed in the first trimester of her first pregnancy as having paroxysmal nocturnal haemoglobinuria. pancytopenia necessitated regular transfusion of blood products. The risks of infection, haemorrhage and thrombosis, in the presence of severe thrombocytopenia, mild neutropenia and prophylactic anticoagulation, posed management challenges. We discuss the pathophysiology of paroxysmal nocturnal haemoglobinuria and the impact of pregnancy on the disorder, particularly on maternal morbidities such as thrombosis. The issues relevant to antenatal and peripartum obstetric, haematological and anaesthetic care for vaginal delivery are considered. Severe thrombocytopenia proved a contraindication to regional techniques and she required general anaesthesia for evacuation of a retained placenta. The post-partum period was complicated by fever and a requirement for blood products. Management of these problems, of prophylactic anticoagulation and subsequent therapy, are discussed.- - - - - - - - - - ranking = 0.16666666666667keywords = haemorrhage (Clic here for more details about this article) |
