Slow continuous quality improvement (SCQI) in anesthesia is a process that allows identification of problems and their causes. Implementing measures to correct them and continuous monitoring to ensure that the problems have been eliminated are necessary. The basic assumption of CQI is that the employees of an organization are competent and working to the best of their abilities. If problems occur they are the consequences of inadequacies in the process rather that in the individual. The CQI program is a dynamic but gradual system that invokes a slower rate of response in comparison with other quality methods, like quality assurance. Spectacular results following a system change are not to be expected an the ideal is slow and continuous improvement.

A SCQI program was adapted by our department in May 1994, according to the recommendations of the American Society of Anesthesiologists. Problem identification was based on 65 clinical indicators, reflecting negative events related to anesthesia. Data were collected using a specially designed computer database. 4 events were identified as crossing previously established thresholds (hypertension, hypotension, hypoxia and inadequate nerve block). Statistical process control was used to establish stability of the system and whether negative events were influenced only by the common causes. The causes responsible for these negative events were identified using specific SCQI tools, such as control-charts, cause-effect diagrams and Pareto diagrams. Hypertension and inadequate nerve block were successfully managed. The implementation of corrective measures for the other events that cross the threshold is still in evolution. This program requires considerable dedication on the part of the staff, and it is hoped that it will improve our clinical performance.

Trauma Registry Database

Trauma Unit, Rambam Medical Center, Haifa

Trauma registry is vital for every trauma center. In 1995, data on all injured patients who reached our trauma unit were collected. 3.040 patients were hospitalized, of whom 415 were transferred from other hospitals. We describe the distribution of the patients to in-patient wards and present the relationship between mortality and injury severity score. 1102 hospitalized patients underwent a total of 1599 operations with an overall mortality of 2.63%.

Subclavian vein thrombosis accounts for approximately 1-2% of recorded deep venous thromboses. It may be primary or secondary, and insertion of a central venous catheter is the most common cause of secondary subclavian vein thrombosis. Traumas, anatomic abnormalities and carcinoma are important additional risk factors for secondary thrombosis. Primary thrombosis of the subclavian veins is known as Paget-Schroetter syndrome. New criteria for its diagnosis include a history of increased upper extremity use prior to onset of symptoms, the presence of a venographically demonstrated thrombus and absence of any definable causes. We describe a 42-year-old woman with a history of intensive physical exertion admitted with swelling, pain and difficulty moving her arm. The diagnosis of primary subclavian vein thrombosis was established from the history of physical effort, results of Doppler ultrasound, and exclusion of other causes of subclavian vein thrombosis. This case suggests that primary subclavian vein thrombosis should be considered in young patients with subclavian vein thrombosis after exclusion of secondary disease.

In a study examining the relationship between patient participation in clinical decision making and levels of anxiety, patients were offered a choice of treatment for ureteral calculus. 42 received information about 2 treatment options, ultrasound fragmentation of the stone through a ureteroscope and extracorporeal shock wave lithotripsy (ESWL), and were asked to choose the method that they preferred. 54 received treatment decided on by the physician without their participation in the decision making process. Anxiety was measured before meeting with the physician, immediately after the meeting and on hospitalization for treatment. The contribution of the patient's perception of participation in the decision- making process and level of education was also examined. There was a decrease in level of anxiety after meeting with the physician only among those who did not actually participate in the decision-making process (p<0.05). There was no change in the level of anxiety among those offered choice of treatment. However, a decrease in anxiety was evident among patients who perceived that they had received information about their illness and its treatment (p<0.01). This was not the case for patients who perceived themselves as participants in decision making unless they had a relatively high-level of education (p=0.05).

In a previous nationwide study, we examined the rate of consanguineous matings in the Israeli Arab community. The average inbreeding coefficient was 0.0192, much higher than that reported for the general population of Israel, 0.0038 in 1956-7. The inbreeding coefficients of 69 Arab villages, towns and cities (excluding the Bedouin in the South) were determined. Knowledge of the inbreeding coefficients of the various local populations is of value for geneticists, pediatricians and gynecologists and for planning suitable health programs.

The use of different types of total hip implants in medical centers in Israel was surveyed. Questionnaires were sent to all orthopedic ward directors in Israel requesting information on the number of total hip arthroplasties performed between the years 1984-1993, the types of implants used, and whether attending physicians or residents perform the operations. 22 of 24 orthopedic wards responded but 1 ward was excluded because only the results for 1993 were reported. 5 wards reported more and 16 fewer than 50 operations a year. 15 different types of implants were in use in Israel in that period, and in 5 wards 5 or more types of implants were used. Only 1 of the wards performed more than 50 operations a year. We conclude that the indiscriminate use of multiple technologies in wards performing few operations can lead to the long "learning curves" previously associated with poor results. Orthopedic surgeons should resist the impulse to introduce new implants, thus improving results and lowering expenditure. The need for regulating the introduction of new implants is emphasized.

Q fever is caused by the rickettsia Coxiella burnetti, an obligate intracellular bacterium acquired by inhalation of infected dust from subclinically infected animals. Q fever may be acute or chronic; the chronic form mostly presents as endocarditis. Immunocompromised states and underlying heart disease are the most important risk factors. Usually the symptoms of Q fever endocarditis are nonspecific and diagnosis is often established very late. New criteria for diagnosis include a single blood culture positive for Coxiella burnetti, positive Q fever serology and characteristic echocardiographic studies. We describe a 49-year-old man with bicuspid aortic valve admitted with fever, weight loss and a new heart murmur. The diagnosis of Q fever endocarditis was established by positive Q fever serology, and an echocardiogram showing vegetations and valvular dysfunction. This case suggests that Q fever endocarditis should be considered in patients with "sterile" endocarditis.

Clavicular fractures make up 45% of shoulder girdle fractures. The clavicle's susceptibility to injury is due to its subcutaneous position and its role as the bony connection between the thorax and the shoulder. In 95% of cases the mechanism of injury is a direct blow to the shoulder. These fractures are usually treated conservatively without surgery. But there are a few such fractures that require surgical repair in order to unite well. 9 patients were operated on for clavicular fractures during 1991-1995. The indications for surgical repair were lateral-third fracture, floating shoulder, neurovascular deficit or nonunion. The methods used were open reduction and fixation with either plate and screws, Kirchner wires, cerclage or a combination. All fractures united well, with no infections or new neurovascular deficits. Good range of shoulder motion and acceptable cosmetic results were achieved in all. 1 patient had functional limitation due to brachial neuritis caused by brachial damage at the time of injury. Indications for surgical repair and the methods used in these cases are similar to those described in the literature. The high rate of union and absence of complications support surgical repair for the few clavicular fractures that are not likely to unite properly.

The increase in mortality and morbidity from multiple trauma due to road accidents, industrial trauma and combat injuries obligates treatment based on emergency systems and trauma centers. Follow-up of the frequency of different types of injury calls attention to increasing involvement of the orthopedic surgeon in primary treatment. This situation calls for appropriate deployment of immediate surgical treatment which will rapidly enable mobility. We present several methods for immediate orthopedic treatment of multiple-trauma patients.

Osteoid osteoma is a primary, benign, bone tumor with a typical X- ray appearance. The diagnosis is usually straightforward when it involves the long bones of the leg. However it may occur in unusual locations, such as in flat and cancellous bones. The following case demonstrates the difficulty in diagnosing it in an extremely rare site. A 25-year-old woman with long-standing anterior, right knee pain had had 3 interventions: 2 diagnostic arthroscopies and a distal, femoral biopsy. Since there had been no improvement in her condition, the diagnosis of osteoid osteoma of the patella was suggested, supported by recent X-ray and scintigraphicfindings. This rare condition was confirmed by biopsy of the upper pole of the patella, a procedure that was followed by complete recovery. 6 years later, she is now completely free of pain and has no clinical or X-ray evidence of recurrence.Review of the literature revealed only 5 previously reported cases of osteoid osteoma of the patella. All were diagnosed relatively late and in 1 the tumor was diagnosed only after total patellectomy. Diagnosis of these rare cases that mimic much more common causes of patello-femoral pain demands a high index of suspicion.

Water intoxication is a serious condition which may be caused by desmopressin overdose, with reversible or irreversible neurological complications. In the past, desmopressin was used in endocrinological centers for the treatment of anti-diuretic hormone deficiency (central diabetes insipidus). Indications for hormone treatment have since widened, especially as an effective solution for nocturnal enuresis. It is now often prescribed in community clinics, and its use has been encouraged by extensive promotion. We describe a 15-year-old boy with primary nocturnal enuresis who started treatment with desmopressin 1 year prior to admission. He was allowed to use the drug without supervision, and drank excessively. The result was water intoxication which required admission for intensive care because of loss of consciousness and convulsions for 36 hours.

Ischemic hepatitis can occur as an acute episode in advanced congestive heart failure (CHF). The mechanism is massive necrosis of the central lobules resulting from acute hypoxia when low cardiac output further reduces oxygen supply, aggravating underlying congestion due to poor venous outflow. We describe a 70-year-old woman with congestive heart failure for 7 years who was admitted with jaundice, vomiting, abdominal pain and oliguria after an episode of hypotension. The diagnosis of ischemic hepatitis was established by a documented episode of severe hypotension, followed by elevation of serum transaminases, a rise in serum bilirubin and LDH levels, prolonged prothrombin time and acute renal failure. Other causes of acute hepatitis, such as a virus or drugs were excluded, and improved liver and renal function followed hemodynamic stabilization. We conclude that ischemic hepatitis should be considered whenever acute hepatitis follows a recent episode of systemic hypotension, especially in the context of concomitant CHF.

32 patients (age range 1.5-22 years) were treated for leg-length discrepancy. 39 lengthening procedures were performed of which 36 involved gradual distraction, in 2 cases chondrodiasthesis was used, and 1 had 1-step elongation. Gradual distraction was done according to Ilizarov, including corticotomy and a 1-week delay before the initiation of distraction. In 33 cases Wagner's external fixator was used, in 2 an Ilizarov frame and in 1 an orthofix fixator. There was complete clinical and radiological union in all but 1 case. Significant correction of leg-length discrepancy and equalization of leg-length was achieved in most patients. In some growing patients over-correction was successfully achieved. The most prevalent complications were pin-site problems, axis deviation, joint subluxation and joint contractures. At latest follow-up most of these complications had disappeared. 91% of the patients either functioned normal or were only mildly limited.

The Serotonin Syndrome

Psychiatric Division, Chaim Sheba Medical Center, Tel Hashomer

The frequent use of selective, serotonin reuptake inhibitors has increased the risk of the serotonin syndrome. This condition is related to stimulation of 5HT1A receptors and is characterized by agitation, confusion, tremor, fever and shivering. A 29-year-old woman and a 69-year-old man with the syndrome are reported, The importance of early diagnosis and treatment is emphasized, and aspects of the syndrome in patients with obsessive-compulsive disorder are presented.

Severe cases of carbon monoxide (CO) poisoning from all over Israel are treated at the Israel Naval Medical Institute with hyperbaric oxygen (HBO). Between 1.11.94 and 15.2.95, 24 cases of CO poisoning were treated. Poisoning was usually due to domestic gas-fired heating systems, CO being the only toxin involved. Since delay between termination of CO exposure and arrival at the emergency department averaged 55 minutes, the level of carboxyhemoglobin measured on presentation did not always reflect the true severity of the poisoning. Poisoning was defined as severe and requiring HBO treatment when 1 or more of the following indications was present: evidence of neurological involvement, cardiographic signs of acute ischemic injury, metabolic acidosis, carboxyhemoglobin level greater than 25%, and pregnancy. 20 (84%) recovered consciousness during the course of 1 session (90 min.) of HBO treatment (p2 2.8 ATA) or immediately thereafter, with resolution of other signs of CO poisoning. 3 required a second treatment session before their symptoms resolved. A patient who arrived in deep coma with severe cerebral edema died. HBO is an important element in the combined treatment of severe CO poisoning. There should be greater awareness of the danger of CO poisoning and the means of preventing it, both among medical staff and the population as a whole, mainly in areas in which cold weather requires use of heating systems, which may be gas-fired.
