In 82 subjects 82 gastric emptying studies using Tc-99m triethylene tetramine polystyrene resin were retrospectively evaluated. All six patients with diabetic gastroenteropathy (GE) had delayed biologic gastric emptying time (BGET) that responded well to metoclopramide (MP) injection. In 11 diabetics without GE, only two had prolonged BGET with good(More)
Biologic gastric emptying time (BGET) was measured in 24 patients with severe diabetes mellitus complicated by vascular damage and peripheral or sensory neuropathy. This population had a BGET of 192 +/- 32.9 min (mean +/- s.e.m. normal 40-85 min). Patients with diabetic gastroenteropathy had prolongation of BGET to 295 +/- 45 (p < 0.05). Metoclopramide(More)

Critical incident monitoring in anaesthesia is an important tool for quality improvement and maintenance of high safety standards in anaesthetic services. It is now widely accepted as a useful quality improvement technique for reducing morbidity and mortality in anaesthesia and has become part of the many quality assurance programmes of many general(More)
Cases are presented in which Tc-99m methylene diphosphonate accumulated in a lung metastasis from well differentiated adenocarcinoma of the colon, and in a hepatic metastasis from oat cell carcinoma of the lung. To our knowledge, this is the first report of Tc-99m phosphonate complexes concentrated in a pulmonary metastasis of colonic carcinoma or in a(More)
Three children with goitrous hypothyroidism had thyroid scans with [Tc-99m] sodium pertechnetate, which showed symmetrically enlarged thyroid glands with uniformly increased activities compared to little activities in the salivary glands and low body background activities. These scan findings, simulating those of Graves' disease, reflect acid trapping of(More)
To evaluate the dual-isotope Schilling test for the diagnosis of pernicious anemia or malabsorption syndrome, 65 studies were selected for clinical correlation. Criteria for pernicious anemia included mean corpuscular volume greater than 100 cu micrometer, serum B12 greater than 100 ng/l, megaloblastic marrow, achlorhydria, reticulocytes greater than 5% on(More)
The electrophysiological mechanisms by which changes in [K+]o suppress and initiate pacemaker activity were studied in guinea-pig isolated sino-atrial node (SAN) superfused in vitro. High [K+]o (10 mM or higher) gradually decreases maximum diastolic potential and action potential amplitude, until only subthreshold responses and eventually quiescence follow.(More)
This study to evaluate the relationship between end-tidal carbon dioxide pressure (ETCO2) and arterial partial pressure of carbon dioxide (PaCO2) included 35 patients between the ages of 18 and 65 years, ASA grade 1 and 2, who had elective craniotomies. Measurements of PaCO2 and ETCO2 were taken simultaneously: 1) 10 minutes after induction of general(More)
This prospective, randomized, study was designed to compare the effect of two different preloading volumes of Ringer's lactate for prevention of maternal hypotension induced by spinal anaesthesia for Caesarean section. Eighty ASA I or II obstetric patients were randomized to two groups. Group 1 (n = 40) received 20 ml/kg of Ringer's lactate and Group 2 (n =(More)
Critical incident reporting is a useful quality improvement technique for reducing morbidity and mortality in anaesthesia. This study analyses 93 cases in Kuala Lumpur Hospital from July 1995 to January 1997. The main incidents during anaesthesia in this study were airway incidents. While human error was identified as the main factor contributing to the(More)
