A 30-year-old woman was admitted to the hospital due to bilateral massive pleural effusion and right lung collapse with severe respiratory distress. She had been undergoing gamete intrafallopian transfer (GIFT) following three years of primary infertility. Ovarian stimulation was done with pure follicle stimulating hormone (FSH) and human menopausal gonadotropin (hMG) under pituitary suppression with leuprolide acetate. Bilateral chest pain and progressive dyspnea occurred six days after preovulatory oocytes with washed motile sperms were transferred laparoscopically to the fallopian tubes. Chest radiography, sonography and computed tomography revealed a massive right pleural effusion with right lung collapse, and a mild left pleural effusion. Abdominal sonography revealed minimal ascites. Supportive therapy including fluid supply and albumin infusion failed to improve the respiratory distress. A tube thoracostomy was performed, resulting in rapid reexpansion of the lung. The respiratory distress improved markedly after drainage of 6,800 mL of pleural effusion over 7 days. Massive serosanguineous pleural effusion with minimal ascites is unusual in ovarian hyperstimulation syndrome (OHSS). Tube thoracostomy is a safe and effective treatment for massive pleural effusion and lung collapse in the case of OHSS.

We have surgically treated six patients with bronchial rupture caused by blunt chest injury in the past 5 years. All injuries resulted from traffic accidents, except in one patient who was hit by a crane. Clinical manifestations included chest pain (n = 6), subcutaneous emphysema (n = 4), and dyspnea (n = 6). Roentgenographic findings were tension (n = 3) or nontension (n = 3) pneumothorax, subcutaneous emphysema (n = 4), pneumomediastinum (n = 3), deep cervical emphysema (n = 5), and delayed collapse of the affected lung (n = 3). Three patients had associated injuries: right clavicle and rib fractures in the first; right humeral, scapular, and multiple rib fractures and left sternoclavicular joint dislocation in the second; and left clavicle fracture in the third. These six patients all underwent immediate tube thoracostomy and then bronchoplasty. Bronchoplasty was performed within 3 days in four patients and on days 16 and 30, respectively, in the other two patients. The affected lung demonstrated full expansion in all patients immediately after bronchoplasty. Follow-up bronchoscopy showed good patency of all bronchi.

Our experience with 18 cases of isolated right ventricular infarction is reported and the literature is reviewed. Chronic lung disease with right ventricular hypertrophy is an important risk factor. Chest pain is the usual symptom at presentation but some cases can have breathlessness, palpitations or syncope. Some cases can have sinus bradycardia, atrial fibrillation or ventricular tachycardia. Atrioventricular block is rare. Cases with pulmonary artery hypertension, extensive right ventricular infarction due to proximal occlusion of the right coronary artery, right atrial infarction or atrial fibrillation can have hypotension and/or systemic venous congestion. A surface electrocardiogram mainly showing changes in leads conventionally considered to represent left ventricle and right-sided chest leads may not show an infarct pattern in some cases. Echocardiography is, therefore, more reliable in diagnosing this condition. The cautious use of small doses of nitrates and diuretics is not hazardous in the absence of hypotension. High doses of steroids and anti-coagulants can be helpful. The prognosis is usually good, although sudden collapse can occur due to ventricular fibrillation, rupture of the right ventricular free wall or a massive pulmonary embolism.

The diagnosis of pulmonary embolism remains enigmatic. Points to look for are: (1) Ninety percent or more of patients with pulmonary embolism have known predisposing factors. (2) Eighty percent or more complain of dyspnea and exhibit hyperpnea (eg, respiratory rate > 20 breaths per minute). (3) Chest roentgenogram abnormalities occur in more than 80% of patients. (4) Seventy percent to 90% of patients complain of chest pain. (5) Either the pCO2 is low or the alveolar-arterial oxygen gradient is high in more than 95% of cases. (6) Twenty percent of patients have normal pO2. (7) Anxiety is present more often than not, and, if present, is no reason to dismiss the cause as "hyperventilation syndrome." Pulmonary arteriography is the "gold standard" for diagnosis, although the combination of ventilation/perfusion scan and noninvasive leg vein studies may decrease its use. An experimental test, the immunosorbent plasma D-dimer assay, seems a promising future screening tool if its reportedly high sensitivity is confirmed. Transthoracic or esophageal echocardiology, if immediately available, may have a place in assessing patients who present with cardiovascular collapse. Early and adequate heparinization coupled with the use of intravenous heparin protocols should lower future mortality rates. Food and Drug Administration approval of low-molecular-weight heparin and heparinoids may revolutionize the management of routine thromboembolism, as these substances are easier to use and less hazardous. A recent British study showed no advantage to anticoagulation beyond 4 weeks for patients with perioperative thrombophlebitis and no other risk factors. In selected cases, thrombolytic therapy, vena caval filters, and invasive embolectomy have been shown to decrease both short- and long-term mortality.

TV-assisted thoracoscopic surgery was performed under local anesthesia by through a single access port to control a continuing air leak in spontaneous pneumotorax. A 75-year-old man was admitted with severe dyspnea and right-sided chest pain. The chest X-ray film showed right lung collapse. A right spontaneous pneumothorax was diagnosed and was treated by chest tube drainage. However, the lung did not re-expand because of a continuing air leak and subcutaneous emphysema developed. TV-assisted thoracoscopic surgery was performed under local anesthesia to treat the persistent air leak on day 12. By endoscopy, the ruptured bulla was double-ligated with an Endoloop through a single access port using lung forceps combined with endoscope. The air leak subsequently ceased and the lung re-expanded. This method is minimally invasive and is very suitable for controlling a continuing air-leak causing spontaneous pneumothorax in a patient.

The objective of our study was to characterise 52 hospital survivors of pre-hospital ventricular fibrillation and record their initial management in hospital. A retrospective review was undertaken of ambulance report forms, hospital notes, and electrocardiograms, in one teaching hospital and three district general hospitals in South Wales, of 53 patients discharged from hospital between February 1987 and April 1992 after resuscitation from pre-hospital ventricular fibrillation by ambulance personnel. Twenty patients showed evidence of acute myocardial infarction (group 1), eight patients had a diagnosis of 'possible acute myocardial infarction' (group 2), and 25 patients had no evidence of acute myocardial infarction (group 3). Nineteen patients in group 1 experienced chest pain before collapse compared with only six patients in group 3 (p < 0.001). Five patients in group 1 had a previous history of ischaemic heart disease compared with 17 patients in group 3 (p < 0.01). A greater proportion of patients in group 3 were taking diuretic medication (15 of 25 vs 4 of 20: p < 0.01) but there was no difference in potassium levels on admission to hospital. Cardiologists were involved in the management of a minority of patients (21 of 53); only eight patients underwent cardiac catheterisation; and only three were referred for electrophysiological studies. Patients in group 3 were more likely to be discharged taking empiric antiarrhythmic drugs (13 of 25) than patients in group 1 (2 of 20) (p < 0.01). Not enough use is made of noninvasive and invasive investigations in the management of survivors of pre-hospital ventricular fibrillation.(ABSTRACT TRUNCATED AT 250 WORDS)

Cardiac [corrected] arrest outcome studies have identified early defibrillation (among other variables) as a strong predictor of survival--with the emphasis placed on minimal delay between arrest and 'shock'. Nurses play a key role in the management of in-hospital cardiac arrest. Often they are first on the scene of an arrest--initiating cardiopulmonary resuscitation (CPR) as well as summoning assistance from the 'advanced life support'/'arrest' team. Thus it is argued that nurses should be willing (and able) to perform defibrillation when required. Notwithstanding this, the community has an expectation (rightly or wrongly) that all nurses are able to appropriately manage a collapse situation. However, research clearly demonstrates that not all nurses are competent in CPR. There is obviously a mismatch between community expectations and reality, which nursing needs to address. Nurses can contribute to the prevention of cardiac arrest in the community by promoting the importance of seeking medical care in the event of chest pain. Furthermore, skilled clinical assessment and recognition of the prodromes of cardiorespiratory collapse may reduce the incidence of in-hospital cardiac arrests.

Coronary angioplasty has been increasingly utilized in patients with extensive coronary disease, severe and acute chest pain syndromes, and poor ventricular function. This process has been facilitated in part by use of circulatory support, including perfusion balloons, intraaortic balloon pumps and cardiopulmonary bypass support systems. Percutaneous cannulation has facilitated elective and emergency application of cardiopulmonary bypass support in patients undergoing high risk coronary angioplasty. A National Registry of 25 centers has accumulated data on 801 elective and 210 emergency support angioplasty patients. Standby cardiopulmonary bypass support of elective high risk patients was associated with fewer complications and less in-hospital mortality in patients other than those with left ventricular ejection fraction < or = 20% and possibly older high risk patients. In elective cases, circulatory support was required in only approximately 7% of high risk patients, although need appeared to be unpredictable. Emergency use of cardiopulmonary bypass support, initiated < 20 minutes from the time of circulatory collapse, was associated with improved patient prognosis. Overall, patients undergoing circulatory cardiopulmonary bypass supported angioplasty had a marked reduction in anginal status, improvement in left ventricular ejection fraction and good (80%) 2-year survival. Although used only occasionally, circulatory support remains an important prophylactic interventional tool for the extremely high risk patient (left ventricular ejection fraction < or = 20%) and a lifesaving emergency technique for the occasional patient with circulatory collapse.

Falls, collapse and confusion are frequent causes of admission to hospital in the elderly, and myocardial infarction (MI) can present atypically. The study was designed to assess the incidence of MI in this group of patients and provide information on the value of screening methods. A total of 142 elderly patients with a mean age of 83 years (range 76-99) were admitted with unexplained collapse, confusion or falls. Serial ECGs and cardiac enzymes were performed. Eighty-two patients (59%) had normal ECGs; of these, 80 (98%) had normal or non-significantly elevated cardiac enzymes; 72/108 patients without chest pain had normal ECGs compared with 10/32 who had chest pain (p < 0.01). Cardiac enzymes were elevated in 5/108 without chest pain and 10/32 with chest pain (p < 0.01). Thirty-two (23%) had chest pain, 14 (10%) had an acute MI. In those presenting with chest pain, 32% had an MI, compared with only 1.9% of those without chest pain (p < 0.01); 18% of patients with an initially abnormal ECG had an MI compared with only 5% of those with a normal ECG (p = 0.02). None of the patients with a normal ECG who were free of chest pain were subsequently proven to have an MI. Cardiac enzymes are often non-specifically elevated in this group of patients due to muscle injury. The incidence of MI is low in patients without chest pain and we would not advocate routine screening with serial cardiac enzymes, unless there is chest pain or an abnormal 12-lead ECG on admission.

A 56 year old man with an implantable cardioverter defibrillator was admitted with chest pain and collapse. Erosion of the left ventricle by an epicardial patch was confirmed by thoracotomy, but surgical repair was impossible. This rare complication should be considered in patients with a history of cardioverter defibrillators implanted by thoracotomy.
