By means of a volumetric respirometer, oxygen consumption and carbon dioxide production were measured in 15 patients with chest trauma who required mechanical ventilation. From the primary measurements, respiratory quotient, daily energy balance, and cumulative energy balance were calculated. There was a moderate increase in metabolic rate, which generally returned to normal during the first week after trauma. A late increase in oxygen consumption was associated with sepsis, large energy deficit, and death in three patients. Carbon dioxide overload caused by excessive feeding caused difficulty in weaning three patients from the ventilator. Measurement of oxygen consumption and carbon dioxide production is helpful in the management of patients with chest trauma and respiratory failure.

During a 7 year period, 38 consecutive patients (31 male and seven female) had repair of an infected sternotomy wound. Their mean age was 56 years (range 13 to 78 years). Sternotomy was performed for cardiac disease in 34 patients. Staphylococcus aureus was the most commonly cultured organism. All patients required sternal debridement, and 17 had resection. Reconstruction was with muscle flaps in 37 patients, omental transposition in one, and both in four. Sixty-seven muscle transpositions were performed (63 pectoralis major, three rectus abdominis, and one latissimus dorsi). The mean number of operations was three (range one to seven). No deaths occurred within 30 days postoperatively. Significant early complications occurred in nine patients. The mean duration of hospitalization was 24.9 days (range 8 to 67 days). All patients were dismissed with a healed sternum. The mean length of follow-up was 24.8 months (range 1 to 81 months). None of the five late deaths were related to sepsis or to wound reconstruction. Recurrent sternal infection occurred in five patients (13.2%). Four of the five patients responded to additional debridement and muscle transposition, and the fifth patient refused further treatment. Of the 38 patients, 33 were alive at the time of this report, 32 with excellent results. We conclude that muscle transposition is an excellent method of management for recalcitrant median sternotomy wounds.

Since 1971 we have seen 15 children with the diagnosis of purulent pericarditis. The causative organism was Hemophilus influenzae in seven, Staphylococcus aureus in three, and five were due to other organisms. In one child the diagnosis was unsuspected until autopsy. The other 14 patients were all treated with intravenous antibiotics to which the organism was sensitive. One child had an immediate pericardiectomy because of tamponade. The other 13 patients had pericardiocentesis for diagnosis and initial therapy. Pericardiocentesis alone resulted in recovery of four patients and failed in nine, including all seven patients with H. influenzae. These nine had recurrent tamponade or a persistent picture of sepsis that was unresponsive to repeated pericardiocenteses and necessitated operative intervention. The procedure used was subxiphoid tube drainage in two patients. One recovered and the other required further operation. The remaining seven patients were treated with pericardiectomy. All pericardiectomy patients recovered without complications or recurrent symptoms. Survivors are asymptomatic with no evidence of pericardial constriction. We recommend immediate pericardiocentesis for diagnosis and initial therapy. Early pericardiectomy should be performed if the causative organism is H. influenzae, if tamponade occurs after initial pericardiocentesis, or if fever persists despite appropriate antibiotics.

Aneurysms of the extracranial internal carotid artery are rare and only 4 cases have been treated at the Wellesley Hospital since 1969. These aneurysms usually present as a painless lump in the neck and the 4 cases to be described manifest unusual presentations. One patient with a history of facial sepsis presented in the Emergency Department with what was thought to be a neck abscess. This was incised and drained before the true nature of the swelling was appreciated. Two patients presented with nerve palsies, one with a hypoglossal palsy due to stretching of the hypoglossal nerve over a large aneurysm and the second with recurrent laryngeal nerve palsy as a result of rupture of a false aneurysm from disruption of a saphenous vein patch inserted following carotid endarterectomy 9 months earlier. The fourth patient presented with a carotid bruit and had a stenosis distal to the aneurysm. Although rare, carotid aneurysms require recognition and early treatment if neurological sequelae are to be avoided.

Patients with primary lung abscess who do not respond to medical management are usually candidates for a lobectomy. Percutaneous tube drainage, used routinely and with good results before the antibiotic era, has nearly been forgotten. Seven patients with lung abscesses and severe sepsis were in critical condition, not permitting pulmonary resection. They were treated by tube drainage. Prompt clinical recovery occurred in all, with complete resolution of abscesses within 4 to 24 days. When medical therapy of lung abscess fails, tube drainage should be considered in preference to a lobectomy. It is safe and curative and avoids unnecessary loss of functioning lung parenchyma. Lobectomy should be considered in patients who have major life-threatening bleeding or massive pulmonary necrosis.

The clinical manifestations and results of management in twenty-five patients treated for infected vascular grafts are reviewed. The overall incidence of infection in this series of prosthetic grafts is 1.4%. Staphylococcus aureus was found to be the single most common infecting organism and multiple organisms were found in nine patients. Therapy was divided into three methods of management: local therapy alone resulted in a mortality of 45% and an amputation rate of 36.3%; partial graft excision resulted in a mortality of 20% and an amputation rate of 60%; total graft excision resulted in a mortality of 22% and an amputation rate of 22% as well. All amputations were above-knee amputations and the most common cause of death was continuing sepsis. The overall mortality of 32% and a loss of limb rate of 44% are testimony to the serious nature of this problem.

Valve replacement in patients with a small aortic anulus can cause difficult technical problems or leave the patient with a significant residual transvalvular gradient. Between August, 1977, and June, 1983, 35 patients with a small aortic root (21 mm or less) underwent aortic valve replacement with Ionescu-Shiley pericardial xenograft valves. They ranged in age from 29 to 76 years (mean 52.8 years) and in weight from 64 to 91 kg (mean 76.3 +/- 3.6 kg). Preoperatively, 26 patients were in New York Heart Association Functional Class III-IV. The valve sizes used were 17 mm in three cases, 19 mm in 16 cases, and 21 mm in 16 cases. There were four hospital deaths (11.4%) resulting from sepsis or low cardiac output. There were no late deaths. Cumulative duration of follow-up was 819.4 patient-months. Twenty-four (78%) of the 31 surviving patients are asymptomatic. Up to the time of review, there have been no episodes of thromboembolism, infective endocarditis, perivalvular leak, valve thrombosis, or primary tissue valve failure. Fifteen patients were hemodynamically evaluated 2 to 47 months (mean 14.3 months) after operation. The average resting transvalvular gradients for 19 and 21 mm valves were 15.1 and 10.8 mm Hg, respectively. Our experience suggests that the Ionescu-Shiley pericardial xenograft valve is a valid alternative in the surgical treatment of patients with a small aortic root.

Dopamine, ethanol, and mannitol were investigated to determine if they could increase pulmonary blood flow and oxygen delivery without significantly increasing intrapulmonary shunt. These drugs were studied in adult patients with respiratory distress following trauma, operation, or sepsis. Intravascular pressure, cardiac output, oxygen consumption and delivery, and limb blood flow and peripheral oxygen delivery were measured in all patients. Hypotensive patients received dopamine in incremental doses of 2 mu g/kg/min until either mean arterial pressure increased 15 mm Hg or heart rate increased by more than 15 beats/min. Ethanol was given as 10% ethanol in 5% dextrose at 2 ml/kg/hr. Mannitol was given as 25 gm of a 25% solution in a single bolus followed by infusion of 8 to 25 gm of 20% solution (mean 10 +/- 2 gm) as a continuous intravenous drip over 1 hour. No drug produced a significant change in intrapulmonary shunt. Ethanol produced significant (p less than 0.05) increases in cardiac index, heart rate, oxygen consumption, and oxygen delivery. Dopamine significantly decreased pulmonary vascular resistance while increasing systemic blood pressure. Visceral blood flow apparently increased while the peripheral vascular response to ischemia remained intact. Mannitol increased oxygen delivery and consumption in both the total body and limb. Thus in patients with adult respiratory distress syndrome (ARDS), increases in pulmonary blood flow can be achieved with several distinct pharmacologic agents without significant increases in intrapulmonary shunt. These increases in flow are generally accompanied by increases in oxygen delivery without increased pulmonary vascular resistance.

In the past 14 years, 42 patients with active infective endocarditis underwent early valve replacement for severe congestive heart failure, major prosthetic dehiscence, intramyocardial abscesses, sepsis, or major embolization. Blood cultures were positive in 40 patients and the valve tissues were positive in two others. All patients received antimicrobials for from 1 to 4 weeks. Drug addiction was noted in 24%, urinary tract manipulation in 7%, dental work in 5%, contaminated prosthesis in 2%, and unknown cause in 62%. Organisms were predominantly staphylococcal (43%) and streptococcal (41%); the remainder were gram-negative (9%) or fungal (7%). The aortic valve was involved in 72%, mitral in 14%, tricuspid in 7%, and both aortic and mitral in 7%. By the New York Heart Association (NYHA) functional classification, 90% (38/42) were in Class III or IV. Operative mortality was 10% (4/42) and all four patients had preexisting renal failure necessitating dialysis. No predominant organism correlated with early deaths. In aortic valve replacement (30 patients), operative mortality was 7%. Postoperatively, 95% (35/37) were Class I or II with one lost to follow-up. Subsequent reoperation was required in five patients (13%) for recurrent endocarditis, with an operative mortality of 20% (1/5). Late death occurred in 45% (17/38). Overall probability of survival was 0.53 at 5 years. For isolated aortic valve involvement, the 5 year survival was 0.58. Survival for native valve involvement was 0.58 and for prosthetic endocarditis, 0.55. This study shows that after at least 1 week of antibiotics, early operation in patients with active endocarditis has an acceptable operative mortality. Clinical improvement is excellent in 95% and more than half survived 5 years or longer.

Six patients who developed infected false femoral artery aneurysms secondary to monitoring catheters are reported. All aneurysms were infected and resulted in systemic sepsis. Initially the origin of the sepsis was not obvious. Findings which suggest this lesion include staphylococci. Appearance of distal petechial hemorrhages should lend a strong suspicion to the possibility of the lesion. Appearance of the pulsatile groin mass completes the diagnosis. Only aneurysmal resection combined with appropriate antimicrobial therapy is curative. For necessary revascularization procedures, autogenous vein grafts should be used when available.
