A web-based Utstein style registry system of in-hospital cardiopulmonary resuscitation in Taiwan.

PURPOSE OF THE STUDY: The Web-Based Registry System on In-hospital Resuscitation (WRSIR) is the first prospective, web-based, multi-site, and Utstein-based reporting system in Taiwan. This study was conducted to evaluate the feasibility of the system in one of the participating hospitals and identify prognostic factors associated with survival. MATERIAL AND METHODS: The WRSIR is an on-line registry system coded with the active server page (ASP) programming method. Information was gathered and entered on-line by trained staff using spreadsheets that could be automatically created according to the updated Utstein in-hospital template. Through the implementation of the system, in a tertiary teaching hospital we evaluated all adults with in-hospital cardiac arrest receiving cardiopulmonary resuscitation between 1 October 2004 and 30 September 2005. The main outcome measures were return of spontaneous circulation (ROSC), survival to hospital discharge, and cerebral performance category score at the time of discharge. Logistic regression analysis was performed to determine independent predictors of survival. RESULTS: A total of 330 cases experienced in-hospital resuscitation. ROSC occurred in 233 cases (71%) and 61 patients (18%) survived to hospital discharge. Thirty-five patients (58%) had a good neurological outcome with the cerebral performance category (CPC) score of 1 or 2 among survivors. The major predictor of ROSC was initial rhythm of VT/VF (adjusted OR 0.36, 95% CI 0.16-0.78). CONCLUSION: This study examined the feasibility of a web-based registry system on in-hospital resuscitation using the Utstein style in an oriental country. It provides a comprehensive and standardised method for on-line registry of data collection, allowing individual hospitals to track each case for quality improvement. A further nationwide registry will enforce the possibility of data analysis and future perspective research of in-hospital resuscitation.

Appendiceal outer diameter as an indicator for differentiating appendiceal mucocele from appendicitis.

BACKGROUND: Patients with appendiceal mucocele (AM) commonly present with features indicative of acute appendicitis. In emergency departments, accurate preoperative diagnosis is crucial to prompt appropriate treatment. This study investigates the clinical and sonographic characteristics of AM, which may prove useful in preoperatively differentiating AM from appendicitis. METHODS: This case-control study compares the clinical and sonographic findings of 16 histologically confirmed AM with sex- and age-matched control subjects (n = 64) with appendicitis by a 1:4 ratio. Conditional logistic regression was applied to estimate the odds ratio (OR) and 95% confidence intervals (CI) of clinical and sonographic parameters associated with AM. RESULTS: Univariate analysis demonstrated that the larger appendiceal outer diameter by sonography was positively correlated with diagnosis of AM (OR, 2.31; 95% CI, 1.42-3.72) and right lower quadrant abdominal pain was negatively correlated (OR, 0.38; 95% CI, 0.17-0.82). However, multiple regression analysis suggested that only outer diameter remained significant (OR, 2.21; 95% CI, 1.36-3.59) after adjusting for age, sex, and right lower quadrant pain. An outer diameter of 15 mm or more was predictive of AM diagnosis, with a sensitivity of 83% and specificity of 92%. CONCLUSION: When the threshold is set at 15 mm, appendiceal outer diameter by sonography is a useful preoperative measurement for differentiating between AM and acute appendicitis.

Nonsurgical management of partial adhesive small-bowel obstruction with oral therapy: a randomized controlled trial.

BACKGROUND: Patients with partial adhesive small-bowel obstruction are usually managed conservatively, receiving intravenous hydration and nothing by mouth. Previous studies have suggested that this approach is associated with longer hospital stays and an increased risk of delayed surgery. We conducted a randomized controlled trial to see if combining standard conservative treatment with oral administration of a laxative, a digestant and a defoaming agent would reduce the frequency of subsequent surgical intervention and reduce the length of hospital stay. METHODS: We identified 144 consecutive patients admitted between February 2000 and July 2001 with adhesive partial small-bowel obstruction and randomly assigned 128 who met the inclusion criteria to either the control group (intravenous hydration, nasogastric-tube decompression and nothing by mouth) or the intervention group (intravenous hydration, nasogastric-tube decompression and oral therapy with magnesium oxide, Lactobacillus acidophilus and simethicone). The primary outcome measures were the number of patients whose obstruction was successfully treated without surgery and the length of hospital stay. We also monitored rates of complications and recurring obstructions. RESULTS: Of the 128 patients, 63 were in the control group and 65 in the intervention group; the mean ages were 54.4 (standard deviation [SD] 15.9) years and 53.9 (SD 16.3) years respectively. Most of the patients were male. More patients in the intervention group than in the control group had successful treatment without surgery (59 [91%] v. 48 [76%], p = 0.03; relative risk 1.19, 95% confidence interval 1.03-1.40). The mean hospital stay was significantly longer among patients in the control group than among those in the intervention group (4.2 [SD 2.7] v. 1.0 [SD 0.7] days, p < 0.001). The complication and recurrence rates did not differ significantly between the 2 groups. INTERPRETATION: Oral therapy with magnesium oxide, L. acidophilus and simethicone was effective in hastening the resolution of conservatively treated partial adhesive small-bowel obstruction and shortening the hospital stay.

ED presentation of acute porphyria.

Abdominal pain is a common complaint for visits to ED. Among the causes of abdominal pain, the acute porphyria may confuse emergency physicians. With wide range of unspecific symptoms and signs, acute porphyria is rarely considered as a differential diagnosis of acute abdomen in ED. Some patients even receive unnecessary surgery. There are 32 patients who visited the ED of National Taiwan University Hospital because of acute porphyric attacks over the past 13 years. Ten patients (3 males and 7 females) were diagnosed with acute porphyria for the first time at ED. The onset of age ranged from 17 to 55 years (mean, 32 years). All of our patients presented with abdominal pain but without fever, dermatologic, and neurologic symptoms that are typically presented in acute porphyria. On the average, most of them repeatedly sought for medical help because of persistent symptoms for 4 times before being definitely diagnosed and thus receiving the optimal treatment. Meanwhile, all patients needed at least 2 kinds of analgesic, and most of them needed narcotic analgesia for pain control before diagnosis. The most commonest point of tenderness is over epigastrium (7 of 10 patients). The laboratory and image studies of our patients were of no diagnostic value for acute porphyria, except for Watson-Schwartz test. In summary, our study revealed that when a patient after puberty with repetitive visits because of severe abdominal pain without reasonable causes and needs narcotics for pain control, acute porphyria should be taken into consideration.

Ultrasound may decrease the emergency surgery rate of incarcerated inguinal hernia.

OBJECTIVE: Manual reduction is the standard procedure for incarcerated inguinal hernia reduction. The role of ultrasound in incarcerated inguinal hernia reduction has not been defined. The aim of this study was to determine whether ultrasound can improve the ability to reduce incarcerated inguinal hernia safely when manual reduction fails and thereby decrease the emergency surgery rate. MATERIAL AND METHODS: Between January 1994 and December 2003, 112 adult patients with incarcerated inguinal hernias were admitted to a university medical center and classified into two groups. Group I consisted of 61 patients who received emergency surgical reduction after the failure of two attempts at manual reduction. In Group II, comprising 51 patients, ultrasound-guided reduction was performed when two attempts at manual reduction failed. Emergency surgical reduction was scheduled if both ultrasound-guided reduction and two attempts at manual reduction failed. The difference in emergency surgery rates between groups I and II was compared. RESULTS: In group I, manual reduction was successful in 55 cases (90.2%) and 6 patients underwent emergency surgery. In group II, manual reduction was successful in 45 cases, ultrasound-guided reduction in 4 cases, 1 reduction was avoided after ultrasonic examination, and 1 patient underwent emergency surgery. The emergency surgery rates in groups I and II were 9.8% and 2.0%, respectively. CONCLUSIONS: Ultrasound can improve the ability to reduce incarcerated inguinal hernia safely when manual reduction fails and may decrease the rate of emergency surgery.

Reversible mitral valve prolapse and mitral regurgitation in children with Graves' disease.

An association between mitral valve prolapse (MVP) and hyperthyroidism has been described in adults. However, the long-term prognosis when associated with significant mitral regurgitation remains unclear. Three consecutive children with Graves' disease were found to have a loud mitral regurgitation murmur (grade III/VI) and echocardiographic evidence of MVP with moderate mitral regurgitation. The cardiac manifestations included palpitations, exertional dyspnea, and exercise intolerance. The electrocardiograms at presentation were sinus tachycardia in all cases. All had hyperthyroidism and positive thyroid antibodies. Exophthalmos occurred in two and appeared later than the cardiac symptoms in one. The cardiac murmur disappeared in all patients when antithyroid agents controlled the hyperthyroidism. Follow-up echocardiography showed normal in one and MVP with mild mitral regurgitation in two. We conclude that MVP and significant mitral regurgitation can occur in children with hyperthyroidism, especially those with Graves' disease. The prognosis is good after adequate medical control of the hyperthyroidism.
