A prospective cohort of 126 patients having long-term central venous catheterization was collected over a 10-month period. The patients were preoperatively assessed for the following risk factors: previous catheter placement, an absolute neutrophil count less than 500/mm3, a platelet count less than 50,000/mm3, a BUN value greater than 60 mg/dL or a serum creatinine level greater than 2.5 mg/dL, a prothrombin time greater than 1.5 times control, recent sepsis, and a Western blot test positive for HIV. The incidence of perioperative complications was 23%. Complications included pneumothorax, arterial puncture, tunnel hematoma, unsuccessful initial placement, and reaction to local anesthesia or blood products. No single risk factor had any statistical significance in predicting a complication. In the subpopulation of patients having two or more risk factors, the complication rate was 50%, with the majority of these being failed placement attempts. We conclude that inserting a permanent central venous catheter is not a benign procedure, but it can be safely done in critically ill patients. Furthermore, evaluation of preoperative risk factors in candidates for catheterization can be helpful to the surgeon with respect to counseling and operative planning.

Carotid loop (CL) surgery involves the permanent externalization of a common carotid artery in a skin tube. The CL facilitates repeated access to the systemic arterial system for blood sampling and blood pressure measurement in laboratory sheep. It eliminates the need for arterial cut-downs and chronic indwelling catheters, reduces the risk of sepsis and infection, and adds flexibility to research protocols. The surgical procedure is aseptically performed under general anesthesia and involves isolation of the common carotid artery, creation of a bipedicled skin tube, and permanent envelopment of the artery in the skin tube. The primary complication is ischemic necrosis with sloughing of the middle of the loop and is usually due to failure to adhere to the critical length-to-width ratio (2.5:1). We have performed 150 CL procedures with an overall success rate of 94%. Nine CL ablations were required, due to necrosis with exposure of the artery (7/9) or stricture formation with loss of patency (2/9). Twenty-two CLs developed complications secondary to partial necrosis, but did not require ablation. Results indicate that the CL is a reliable method to ensure repeated access to the systemic arterial system in sheep. A modification of the standard CL procedure in which the artery is surrounded by a skin tunnel rather than enclosed in a skin loop was performed in 10 sheep. Preliminary results indicate significant reduction in the incidence of complications associated with the standard CL.

Eight patients with large panniculi are described where severe problems with hygiene, immobility, and chronic infection were caused by the lymphedematous, chronically infected pannus. Protracted nonsurgical management of the infected panniculus had failed in all 8 patients. Wedge resection without fat undermining removed diseased tissue. Infection and sepsis were eliminated and ambulation was restored in all patients. Formerly immobile patients were returned to normal activity. Significant self-induced weight loss was not observed in a 2-year follow-up period; weight gain, however, was not experienced. The primary anesthetic method was thoracic epidural reducing the requirements for general endotracheal anesthesia. The chronically infected pannus is a surgical problem deserving earlier recognition and resection.

Although gut permeability increases and bacterial translocation occurs under certain pathological conditions, it remains unknown whether gut absorptive capacity (GAC) is altered early after the onset of sepsis. The aim of the present study was to investigate this and also to determine whether diltiazem has any effect on GAC in early sepsis. Rats were lightly anesthetized and cecal ligation and puncture (CLP) was performed. A nasogastric tube was inserted, cannulation of various blood vessels was carried out, and the animals were allowed to recover from anesthesia. One hour after CLP, one group of animals received a 1-ml bolus of normal saline intravenously, and another group received diltiazem, 400 micrograms/kg body wt. Sham animals had no CLP performed. GAC was determined by the D-xylose absorption test at 2 and 4 h after CLP. One hour after the administration of D-xylose via the nasogastric tube, its concentration in portal blood was determined colorimetrically. Results show that GAC is significantly depressed at 2 and 4 h after CLP despite the maintenance of normal blood pressure, central venous pressure, and portal pressure. Administration of diltiazem restored GAC to normal levels at 4 h after CLP. Thus diltiazem is a useful adjuvant in the treatment of sepsis because it restores gut absorptive capacity to normal and allows for early enteral nutrition.

This is a report of our experience with 22 cases of large unruptured omphaloceles treated by amnion inversion during the period 1973 through 1990. The method is characterized by three stages: (1) a silastic sheet is sutured directly to the skin around the amniotic membrane, under local anaesthesia, without dissection between the skin and the amnion; (2) the reduction of herniated viscera into the abdominal cavity is achieved by squeezing the sheeting using a specially modified stapler; and (3) the amniotic membrane is preserved intact, and inverted into the abdominal cavity at the time of abdominal wall closure. Of the 22 infants, 19 survived with satisfactory results. Two patients died of multiple associated anomalies, and the remaining patient died of sepsis arising at the time of the final abdominal closure. This procedure has proved to be effective and safe for high-risk patients with congenital heart diseases, anal atresia, tracheoesophageal fistula, or bronchial stenosis and prematurity. The practical aspects of the procedure, as well as its advantages and pitfalls, are illustrated.

Infection of Pekin ducks with duck hepatitis B virus is a useful model for studying the hepadenoviruses, of which human hepatitis B virus is the prototype. The utility of this model has been limited, however, by the difficulties associated with anesthetizing and obtaining liver biopsies from ducks. We developed a technique using Telazol (13 mg/kg) to anesthetize ducks before surgical biopsy of the liver in ducks infected with duck hepatitis B virus. Eight Pekin ducks infected with duck hepatitis B virus underwent serial biopsies at 4- to 5-week intervals. There was one perioperative death in 34 surgical procedures with no evidence on intra-abdominal sepsis or wound complications. Telazol can be used safely and humanely to anesthetized ducks without the need for general endotracheal anesthesia.

Seven pregnant women with symptomatic hydronephrosis had sonographically guided percutaneous nephrostomy for pyosepsis (five patients) or for pain with azotemia (two patients with renal transplants). Antibiotics had been ineffective in controlling pyosepsis in each patient; retrograde ureteral catheterization via cystoscopy was unsuccessful in one patient. After percutaneous nephrostomy, prompt clinical improvement was observed in all patients (i.e., sepsis was relieved and pain abated). Labor was not induced in any of the patients, and no adverse effects occurred to any fetus or mother. Eleven (eight percutaneous nephrostomy, three catheter exchanges) of the 12 procedures were done without conventional radiography and with sonographic guidance alone. After percutaneous nephrostomy, maneuvers to obtain a diagnosis and to treat the obstruction (if necessary) were delayed until after delivery. The causes of ureteral obstruction were calculi (four patients) and a gravid uterus (three patients). After delivery, stones were removed either percutaneously (one patient) or cystoscopically (two patients) or passed spontaneously (one patient); resolution of obstruction by the gravid uterus was proved by Whitaker test after delivery. Sonographically guided percutaneous nephrostomy is an effective and safe method to treat pregnant women who have symptomatic obstructive hydronephrosis associated with either pyosepsis or azotemia. The procedure is rapid, requires minimal anesthesia, has no radiation, and is safe for the fetus. The technique is a useful and perhaps preferable alternative to more invasive surgical therapy or retrograde stenting.

One way to nutritionally support patients who cannot swallow is to administer formula directly into the stomach. Placing a gastrostomy tube percutaneously using endoscopy avoids the risks of general anesthesia and wound healing that accompany surgical gastrostomy. Although certain conditions (eg, sepsis, coagulation disorder, portal hypertension) are contraindications to the procedure, it can be done in patients who have had previous abdominal surgery and in those with severe illness. A commercially available feeding formula is used. The type chosen and the frequency of administration are based on the patient's specific needs. With regular medical monitoring and daily care of the gastrostomy site, appropriately selected patients may be safely maintained with enteral feeding for months. An advantage of the percutaneously inserted tube is that it is easily removed when the patient regains the ability to eat, and the fistula heals rapidly.

Sinusitis is an important cause of sepsis in the critically ill patient and may be difficult to diagnose. Four patients admitted to the surgical intensive care unit with closed head trauma were found to have sinusitis as the cause of persistent bacteremia. All patients received pharmacologic doses of corticosteroids for treatment of head injury and had prolonged nasotracheal and/or nasogastric intubation. A bedside procedure was used for diagnosis and management. Under local anesthesia, a 16-gauge angiocatheter was inserted under the inferior turbinate and into the maxillary sinus. After purulent fluid was aspirated, the sinuses were irrigated with normal saline. All four patients defervesced within 24 to 48 hours of this procedure, and facial x rays demonstrated clearing of the maxillary sinus. It was concluded that: 1) Sinusitis is a complication of closed head trauma in critically ill patients and should be included in the differential diagnosis when persistent bacteremia occurs; 2) The use of corticosteroids in the treatment of head injury may increase the risk of sinus infection; 3) Facial x rays showing air-fluid levels and/or opacification are a valuable screening test for paranasal sinusitis; and 4) bedside aspiration of the maxillary sinus is an effective diagnostic and therapeutic technique for management of sinusitis in the critically ill.

In 1987, Yeager et al. reported that intraoperative epidural anesthesia with local anesthetics and postoperative epidural analgesia with opiates diminished postoperative morbidity. In our first clinical trial on this topic, the better postoperative analgesia with epidural bupivacaine-fentanyl failed to improve the outcome after major abdominal operations over that obtained with parenteral piritramide. This randomized controlled investigation was designed to assess whether intraoperative epidural anesthesia with bupivacaine plus light general anesthesia and postoperative epidural analgesia with morphine would diminish the overall rate of postoperative complications after major abdominal operations compared with general anesthesia (without epidural) followed by patient controlled analgesia with morphine, and with intraoperative epidural anesthesia with bupivacaine and light general anesthesia followed by postoperative bupivacaine-morphine analgesia. METHODS. A total of 292 patients undergoing infrarenal aortic bypass operation, gastric resection, gastrectomy, duodenum-preserving pancreatic resection, Whipple's operation or cystectomy and neobladder formation were randomly divided into three groups: 1. PCA group (patient controlled analgesia, n = 107): patients were operated on under general anesthesia (midazolam, fentanyl, N2O/O2, if necessary with addition of halothane, enflurane or isoflurane; muscle relaxation with pancuronium bromide). Postoperative management consisted in patient-controlled analgesia with morphine (Prominject), bolus 2 mg, lock-out 5 min (recovery room, intensive care unit) or 15 min (surgical ward). 2. EBM group (epidural bupivacaine+morphine, n = 95): operation under light general anesthesia (midazolam, low-dose fentanyl, N2O/O2, pancuronium bromide). In addition, a mixture of bupivacaine (0.25%) and morphine (60 micrograms/ml) was infused (approximately 0.1 ml/kg.h) via an epidural catheter during and after the operation (approximately 72 h). 3. EM group (epidural morphine, n = 90): operation under the same kind of general-epidural anesthesia as in the EBM group. Postoperatively, epidural injection of morphine (0.05 mg/kg in 10 ml of saline) on request up to the 3rd postoperative day. Quality of analgesia (at rest and when patients coughed vigorously), strength of cough, and rate-pressure product were recorded at 8:00 h, 12:00 noon, 16:00 h and 20:00 h on the 1st, 2nd and 3rd postoperative days. Incidence and intensity of all postoperative complications (cardiovascular, pulmonary, renal and other organ failure, reoperations, major infection, sepsis, thromboembolism, metabolic and mental disturbances) were assessed from the day of operation until discharge or death (n = 10), respectively. RESULTS AND DISCUSSION. In the PCA and EM groups analgesia was equal but of slightly inferior quality compared with the EBM group. The ability to cough was best in the EBM group and significantly worse in the PCA and EM groups, with no difference between the last two. (ABSTRACT TRUNCATED AT 400 WORDS)
