A 67-yr-old man who suffered from pulmonary embolism following abdominal surgery was reported. The patient received left hemicolectomy and cholecystectomy for cancer of descending colon and cholecystolithiasis, respectively. Anesthesia was maintained with enflurane 0.6-1.0% and pancuronium combined with epidural analgesia. The anesthetic course was uneventful. But after leaving operating room the patient showed severe hypoxemia without abnormal shadow on chest X-P and other abnormal laboratory values. The cause of hypoxemia was unclear, but on the fourth postoperative day pulmonary scintigrams revealed pulmonary embolism. Then 12000 units.day-1 of heparin infusion was started. After 10 days of anticoagulant therapy, the hypoxemia improved and he was discharged on 28th postoperative day. Although pulmonary embolism is a rare disorder, we have to take it into consideration as one of the causes of postoperative hypoxemia.

We have studied the effect of extradural analgesia on postoperative venous thrombosis in patients undergoing knee arthroplasty. Forty-eight patients were allocated randomly to receive either general anaesthesia or extradural analgesia with local anaesthetics for 3 days. All patients wore compressive elastic stockings and no anticoagulant drugs were administered. Bilateral venography was performed 10 days after surgery. Continuous extradural analgesia did not impede mobilization of the patients. One case of nonfatal pulmonary embolism occurred in a patient who received general anaesthesia. The use of continuous extradural analgesia resulted in a significant difference in the total incidence of deep vein thrombosis (18% compared with 59% after general anaesthesia (P = 0.02]. The incidence of calf vein thrombosis was 12% compared with 45% after general anaesthesia (P = 0.05).

Fifty-five patients undergoing total hip replacement using epidural analgesia were allocated to the combination of low dose heparin and dihydroergotamine (5.000 IU heparin and 0.5 mg dihydroergotamine given subcutaneously every twelve hours) (n = 27) or to placebo (n = 28). All patients wore thigh-length graded compression stockings. The patients were screened for deep venous thrombosis by means of the 99mTc-plasmin test and the diagnosis of deep-vein thrombosis was confirmed by ascending phlebography. Three patients in each group developed unilateral deep-venous thrombosis. One patient in each group developed non-fatal pulmonary embolism.

The effect of changing the volume of cerebro-spinal fluid (CSF) before spinal anaesthesia with 3 ml of isobaric 0.5% bupivacaine was investigated in 60 elderly (58-77 years) orthopaedic or urological patients. The patients were randomly allocated to three groups. They received the spinal anaesthetic either with or without the aspiration of 3 ml of CSF. In the third group a mixture of 3 ml of aspirated CSF and 3 ml of 0.5% isobaric bupivacaine was given. Pin-prick analgesia and motor block were tested during the induction and recovery. The only statistically significant difference between the groups was in the time-lag from administration to maximum spread of pin-prick analgesia, which was shortest in the group without aspiration (mean 19.5 min, other groups 29-30 min). The mean maximum level of analgesia was T6-T7 in each group. The anaesthesia was satisfactory in most cases. One death occurred because of a massive pulmonary embolism. The clinical significance of aspirating CSF before attempting spinal anaesthesia with 3 ml of 0.5% isobaric bupivacaine was found to be small.

In a prospective study of 50 patients subjected to major abdominal surgery, the frequencies of postoperative deep vein thrombosis and pulmonary embolism were analysed. The patients were randomized to one of two groups receiving either neurolept anaesthesia or neurolept anaesthesia combined with thoracic epidural analgesia. Five patients were excluded. No special anti-thrombotic prophylaxis was administered. Deep vein thrombosis was diagnosed with the 125I-fibrinogen test and pulmonary embolism with pre- and postoperative lung perfusion scintigraphy combined with lung X-ray. Patients with positive scintigraphy were subjected to pulmonary angiography for verification of the diagnosis. Deep vein thrombosis was treated when diagnosed. The frequency of deep vein thrombosis was equal in both groups (38%). No patient with pulmonary embolism was recorded during the first seven days after operation. It is concluded that the addition of thoracic epidural analgesia to neurolept anaesthesia does not alter the postoperative frequency of deep vein thrombosis in patients subjected to major abdominal surgery. Early diagnosis and treatment of postoperative deep vein thrombosis might prevent pulmonary embolism. Problems encountered in the diagnosis of postoperative pulmonary embolism are discussed.

A prospective study of thrombo-embolism after total hip replacement in epidural analgesia was carried out in 116 patients, randomly allocated to dextran 70 or low-dose heparin combined with dihydroergotamine (HDHE). Amounts of blood loss and transfused bank blood did not differ significantly between dextran 70 and HDHE prophylaxis. There was a lower incidence of femoral deep vein thromboses in patients given dextran prophylaxis as compared with those on HDHE (P less than 0.05). However, the total frequency of DVT and the frequency of pulmonary embolism did not differ between the two groups. There was no case of fatal pulmonary embolism. The side effects were major bleeding complications in 7 per cent of the HDHE group as compared to none in the dextran group. No anaphylactic reaction was noted from dextran 70 using hapten-dextran prophylaxis.

The effects of continuous epidural anesthesia and of general anesthesia on the incidence of thromboembolism following total hip replacement were studied. Sixty patients were randomly allotted to one of two groups receiving either epidural or general anesthesia. Epidural anesthesia (N = 30) consisted of 0.5% bupivacaine with epinephrine intraoperatively; for pain relief in the postoperative period (24 h), 0.25% bupivacaine with epinephrine was given every 3 h. General anesthesia (N = 30) consisted of controlled ventilation with N2O-O2 and intravenous fentanyl and pancuronium bromide; postoperatively, narcotic analgesics were given intramuscularly on demand for pain relief. Significantly lower frequencies were found following epidural anesthesia than after general anesthesia in deep venous thrombosis involving the popliteal and femoral veins (13% and 67%, respectively), deep venous thrombosis involving both calf and thigh veins (40% and 77%), and pulmonary embolism (10% and 33%). Possible explanations for these differences include increased circulation in the lower extremities, less tendency for intravascular clotting to occur, and more efficient fibrinolysis in association with continuous epidural anesthesia. The decrease in blood loss associated with epidural anesthesia with lower transfusion requirements also might play a role. Epidural analgesia prolonged into the postoperative period, in addition to other appropriate thromboprophylactic measures, should be of value in patients undergoing operations associated with a high risk of thromboembolic complications.

An intensive treatment of patients undergoing thoracic surgery is important, foremost because of the extensity of the surgical procedures and the generally poor condition of the patients. As a first stage of preoperative preparation an evaluation of the functional capacity of the vital organs (heart, lungs and kidneys) is performed, and the most important infection's focci of the oro-pharynx, tracheobronchial tree, urinary tract and skin have to be detected and treated. Respiratory physiotherapy before the surgery improves the ventilatory function, enabling the patient to breath regularly and effectively cough, wherewith a bronchial spasm is prevented and bronchopulmonary infection limited. Before surgery any hypovolaemia, anaemia, hypoproteinemia and dysproteinaemia should also be corrected; in such patients the parenteral alimentation (hyperalimentation) through the central venous catheter, is also important. Immediately following the operation a continuous supervision of vital functions (usually managed by well-experienced surgical nurses) is very essential. Isothermia, isovolemia, a correct oxygenation and analgesia should be maintained permanently. To loose sight of hypoventilation and hypoxia can likely induce respiratory insufficiency. Symptoms indicating tracheal intubation and mechanical ventilation should be watched for and treated at the right moment. Following the surgery, prevention of pulmonary atelectasis and pneumonia, providing an effective thoracic drainage, and respiratory physiotherapy is of utmost importance. The prophylaxis of postoperative pulmonary embolism in particularly jeopardized patients consists in the administration of heparin. Antibiotics in accordance with antibiogram (material: samples taken by a catheter or by bronchoscope from the lung directly).

Sixty elderly patients were given at random either epidural analgesia with bupivacaine 0.75% or general anaesthesia with thiopentone, fentanyl, pancuronium, N2O/O2 for total hip replacement. Preoperatively the patients were of equal physical status with normal and similar laboratory values. All patients were mentally normal for their age. On the 1st postoperative day, the general anaesthesia group had a significantly lower than PaO2 than the epidural group (P less than 0.025). PaO2 in the general anaesthesia group was significantly lower than the preoperative value on the 1st and 3rd days (P less than 0.001 and P less than 0.01, respectively). None of the 29 patients in the epidural group but seven of 31 patients in the general anaesthesia group has significant mental changes postoperatively (P less than 0.01). Five of these patients still had mental changes which reduced the quality of life several months later. In the general anaesthesia group one patient died from acute myocardial infarction. Low postoperative PaO2 might have contributed to this death. Two patients in the epidural group had symptoms of pulmonary embolism postoperatively. Thus elderly patients appear to do better after hip replacement with less deterioration of cerebral and pulmonary functions when given epidural analgesia than when surgery is performed under general anaesthesia. These patients should therefore be offered epidural analgesia whenever possible.

The immediate effects and long-term results are reported of thoracoscopic pleurodesis in 225 patients (158 men, 67 women) treated for persistent or recurrent spontaneous pneumothorax. The procedure was performed by combined local and neurolept analgesia with direct visual exploration of the pleural space through a rigid thoracoscope. The technique included electrocoagulation of small pleural blebs, followed by regional application of fibrin and insufflation of talc powder. The main indications were a first event which persisted more than 7 days despite chest-tube suction drainage in 27% (n = 61) or a recurrent event in 73% (n = 164). The procedure provided primary success in 96.4% of the patients. Only 8 patients (3.6%) required surgical intervention including parietal pleurectomy. Perioperative complications were pharmacologically induced respiratory failure (n = 5), generalized subcutaneous emphysema (n = 8), bleeding by cutting adhesions (n = 5) and Horner's syndrome (n = 2). However, no fatal complications occurred which could be ascribed to the procedure and all patients were discharged from the hospital after an average of 12.3 days except one who died of pulmonary embolism 5 days after thoracoscopy. Long-term follow-up over a mean period of 4.1 years revealed an ipsilateral recurrence rate of 10.2% (n = 24), 16% of the patients complained of sporadic pains at the site of insertion, 51% still had diffuse thoracic pains and 2.4% reported occasional attacks of dyspnea. Spirometric lung function tests showed normal values in 89%. The immediate and longterm results show thoracoscopic pleurodesis with fibrin and talcum to be a safe and effective method for treatment of patients with persistent or recurrent pneumothorax.
