Uncontrolled bleeding of the gastrointestinal tract.

PURPOSE OF REVIEW: Acute gastrointestinal bleeding is a frequent emergency situation, whose incidence will likely rise as a result of the increasing use of direct anticoagulants and of the medical progresses resulting in longer life expectancy with underlying comorbidities. Updated guidelines and improvements in the diagnostic and therapeutic tools are now available and will likely improve the management of massive gastrointestinal bleeding in the near future. RECENT FINDINGS: The assessment of severity has been improved by validated scores useable upon admission. Massive blood transfusion protocols and specific care in case of bleeding of patients treated with direct anticoagulants, including concentrates of coagulation factors and monoclonal antibodies are now available. The endoscopic management has been facilitated by the use of hemostatic powders and by the use of self-expanding metal stents in case of variceal hemorrhage. New diagnostic tools include emergency video-capsule endoscopy, multiphasic computed tomography angiography and enterography. SUMMARY: The implementation of multidisciplinary diagnostic and therapeutic algorithms for the management of massive bleeding requires a close collaboration between emergency physicians, intensivists, endoscopists, radiologists and surgeons. A sequential strategy involving each of these specialists is desirable for a successful management of acute and massive gastrointestinal bleeding.

Outcome of permanent vascular access for haemodialysis in patients with end-stage renal disease in Cameroon: results from the pilot experience of the Douala general hospital.

Background Chronic Kidney disease is a major health problem in the world. Native arteriovenous Fistula (AVF) is well established as the best vascular access for haemodialysis. Little is known about the outcome of AVF in sub-Saharan Africa. We aim to analyze the outcome of patients undergoing AVF creation during the pilot program established at the Douala general hospital (DGH). Method This was hospital-based, longitudinal study with a retrospective phase (April 2010-January 2014) and a prospective phase (January 2014-April 2014). All consecutive patients operated for AVF creation were included in this study. Socio-demographics data, functionality, and complications were analyzed. Results Eighty-one patients including 52 men were enrolled in this study (49 prospectively and 32 retrospectively). The mean age was 52, 3 years (range 18-81 years). Hypertension (66, 7%), diabetes (17, 3%), and HIV (8, 6%) were the most observed co-morbidities. About 96.3% of AVF were native and 3.7% were prosthetic graft. Radiocephalic AVF was performed at a rate of 77.8%. The primary function rate was 97.7% and the mean follow-up period 43.4 weeks. The overall rate of complications was 44.4% of whom 30.5% were early, 30.5% secondary, and 39% lasted. The treatment of these complications was conservative in 48.7% of cases. Conclusions The results of the pilot program of AVF creation at the DGH are encouraging. However, the sustainability of this project requires human capacity building.

Does infusion of colloid influence the occurrence of postoperative nausea and vomiting after elective surgery in women?

BACKGROUND: The impact of the type of fluid on postoperative nausea and vomiting (PONV) is not well defined. In this study we investigated the effects of colloids or crystalloids on PONV when given in addition to a background minimal crystalloid infusion in a female population of surgical patients. METHODS: This prospective, randomized, double-blind study included 115 women undergoing gynecological or breast surgery who were randomly allocated to receive hydroxyethyl starch (HES) 130/0.4 or normal saline in addition to a fixed background infusion of 5% dextrose in 0.45% saline at a flow rate of 0.5 mL x kg(-1) x h(-1). A bolus of 500 mL of the study fluid (HES or normal saline) was infused before the induction of anesthesia, followed by a continuous infusion of 1 mL x kg(-1) x h(-1) adjustable according to hemodynamic needs. The primary outcome variable was the incidence of PONV during the 24 h postoperative period. Secondary end points were the need for antiemetic rescue therapy, incidence of hypotensive episodes, pain scores, and need for additional analgesia. RESULTS: Nausea occurred in 11 of 56 patients who received HES and in 11 of 58 patients who received saline (P > 0.05). There were no differences between groups in the incidence of vomiting. There were no differences between the groups regarding antiemetic rescue therapy, hypotensive episodes, pain scores, or need for opioids. CONCLUSIONS: In surgical procedures with minimal blood loss and minimal fluid shifts, the type of fluid replacement administered (colloid vs 0.9% normal saline) has minimal effect on the incidence of PONV.

Combined ultrasound and nerve stimulation-guided thoracic epidural catheter placement for analgesia following anterior spine fusion in scoliosis.

Anterior spine fusion by thoracotomy is indicated for the treatment of idiopathic scoliosis. Although epidural (EP) analgesia represents the most effective way to provide adequate analgesia after thoracotomy, scoliosis patients have substantial anatomic variations that make EP catheter placement more difficult and often contraindicated. This case report describes a safe, effective technique for placing a thoracic EP catheter in a young patient undergoing anterior spine fusion surgery by thoracotomy. The procedure was guided by both ultrasound (US) and electrical stimulation of the Tuohy needle and catheter. The combination of US and nerve stimulation in this setting may be associated with easier, potentially safer, and more accurate insertion.
