The purpose of this study was to identify the best method of autologous blood transfusion to be applied in an East African hospital. One hundred and nine consecutive patients for whom major blood loss was anticipated were enrolled. Seventeen patients donated 1 unit of blood 3 days preoperatively and 92 underwent acute isovolaemic haemodilution prior to induction of anaesthesia. For the haemodiluted patients a 2:1 ratio of sterile pryogen-free saline to collected blood was used. One of the 16 patients from whom 2 units were withdrawn by haemodilution experienced hypovolaemia which was rapidly restored by additional transfusion of colloid. Of the patients who donated blood preoperatively only 23.5% were autotransfused compared to 98.9% of the haemodiluted patients. Of the latter 23.9% (22) had an intraoperative blood loss exceeding 15% of their total blood volume and 7.6% (7) lost more than 25%. Only one received homologous blood in addition. For hospitals with limited blood bank facilities and regular cancellation of surgery, the use of acute isovolaemic haemodilution is recommended. A 3:1 ratio of saline to blood is now advised when 1 unit is withdrawn and a part replacement with crystalloid when 2 units are collected.
In order to make informed purchasing decisions about practice management software, dental professionals must first assess their needs by determining the types of tasks they expect from a system and then compare that list against the features offered by each system. Because technology is changing rapidly, much of what was advanced a few years ago is now considered basic. Three general levels of sophistication are discussed, with attention to the complexity of features that can be expected to be found at each level.
All medical out-patient appointments of a firm of three consultants at the Royal Hospital for Sick Children were reviewed over a four week period. Of 758 appointments initially offered, 490 (64%) patients attended; 19% of patients cancelled and 17% did not attend without cancelling. Delay from referral to attendance ranged from 0 to 9 weeks. The characteristics of those patients experiencing prolonged registrar-only follow-up are described. The content of subsequent letters to family practitioners was usually adequate compared to accepted standards. Delays in dictation of letters were usually short in comparison to delays in typing. Such delays and the intervals between consultant review of out-patients may prove costly to providers. Potential improvement strategies are discussed.
