Problems facing a patient with severe dyspnea secondary to diaphragmatic herniation are hypoxia, hypercarbia and respiratory acidosis, and cardiovascular instability. It is easy to precipitate a crisis in these patients during anesthetic induction as a result of stress, bad positioning, induction of pneumothorax, or inappropriate anesthetic technique. These patients require a smooth, stress-free perianesthetic period with preoxygenation, positioning with the affected side down, rapid intravenous induction, endotracheal intubation, and mechanical ventilation. Maintenance with isoflurane is preferred, and nitrous oxide should be avoided. Close monitoring of the cardiovascular and pulmonary systems is essential. Recovery from anesthesia should include oxygen supplementation, pleural drainage, and local analgesia if required.

Thoracic trauma is uncommon in children. It should not be managed any more as adult's trauma. We present our experience with 85 children form 1 to 16 years of age, presenting severe thoracic trauma treated in Lausanne, Switzerland, between 1976 and 1990. The specific features of diagnosis, treatment and outcome are presented. Most of them were involved in traffic accidents (62%), 55% had multisystemic injuries. The mortality rate was not a function of the Injury Seventy Score as in adults, but was only related to the Glasgow Score. Only 3 patients (3.5%) had hemodynamic instability on admission in relation with their thoracic injury. Patients with intrathoracic lesions showed dyspnoea (65%), cyanosis (25%), or clinical suspicion of a pleural effusion or a pneumothorax (47%). However 12 children had an asymptomatic severe thoracic injury. In 53 patients (62%) the auscultation was found abnormal either with absent or diminished breath sounds or other pathological findings. 10 out of 26 cases of pneumothorax could be suspected by percussion dullness. Chest X-rays showed a lesion in 76% of cases. Only 30% of the pneumothorax were associated with visible rib fractures. 10 children suffered from 4 to 12 fractures of the ribs (mean 6.6). None of these patients presented a flail chest as in adults, even when multiple rib fractures existed. 31 thoracic drainages were performed, during a mean period of 3.3 days. 30 patients were intubated and ventilated, 22 of these due to a neurosurgical condition. All patients had physiotherapy starting on day 2, under analgesia if necessary.(ABSTRACT TRUNCATED AT 250 WORDS)

A case is reported of acute respiratory failure occurring during upper abdominal surgery in a patient not previously known to have chronic respiratory failure. Preoperatively, this 68 year old patient presented with mild obesity, slight effort dyspnoea and paralysis of the right hemidiaphragm, a sequela of polytrauma she suffered the year before. Respiratory tests were not considered useful with regard to the results of clinical examination. Moreover, she had already several previous general anaesthetics without any problems. A thoracic epidural anaesthesia was performed with a mixture of 150 mg lidocaine, 37.5 mg bupivacaine with adrenaline and 100 micrograms fentanyl, injected in the T8-T9 epidural space via a catheter. Ten minutes after the starting of surgery, the patient became agitated and complained of difficulty in breathing. Blood gas analysis showed hypercapnia, with respiratory acidosis (Pao2: 28.19 kPa; Paco2: 9.2 kPa; pH 7.273). Clinical examination revealed a bilateral Horner syndrome (T1-T4 sympathetic blockade). The patient was intubated and ventilated after adequate sedation. She was extubated 3 h 30 min after the initial epidural injection. Epidural analgesia was maintained during 72 h, with 0.1% bupivacaine, with no recurrence of respiratory failure.

We report a 21-year-old male patient suffering from acute myeloid leukemia and concomitant thrombocytopenia. Following a diagnostic thoracotomy-which revealed Aspergillus pneumonia-he developed respiratory insufficiency and dyspnea. A thoracic epidural catheter was inserted and epidural morphine treatment led to improved ventilation. No clinical signs of pathological epidural processes were noticed during the treatment. The patient died of Aspergillus sepsis 26 days after catheter insertion. Autopsy revealed bacterial growth in the epidural space with slight infectious tissue reactions as well as an epidural hematoma. No evidence of spinal cord compression was found at autopsy. The development of epidural infection or hematoma seems to be a possible complication of epidural analgesia in patients suffering from impaired defense mechanisms or thrombocytopenia. These risk factors should be taken into account when epidural analgesia is considered. We suggest that the platelet count should be determined beforehand in patients suspected of having thrombocytopenia (e.g. cancer, pre-eclampsia).

A 41-year-old woman sustained bilaterally multiple rib fractures in a severe car accident. She developed severe pain-related dyspnoea. On-demand analgesia with tramadol (by pressing a button the patient could self-administer single doses of 20 mg) rapidly decreased the pain and respiration became almost normal. Daily doses of about 400 mg were sufficient. The ability to self-administer the analgesic clearly was an important psychological factor in the good response to the usually relatively weakly effective opioid.

The clinical details are presented of 29 fatal cases of pleural mesothelioma in the majority of which there was a history of exposure to asbestos during dockyard work in Portsmouth. Chest pain, breathlessness and weight loss dominated the clinical picture. Analgesia and repeated pleural aspirations provided temporary relief but symptoms invariably progressed. The mean survival time was 39 weeks. Only one patient survived longer than 2 years from hospital presentation. At autopsy, extensive local spread was usual but a high proportion of patients also had metastases at distant sites.

We have prospectively treated 36 patients with flail chest using a treatment protocol for limited use of mechanical ventilation. Age of the patients ranged from 6 months to 83 years. Patients were divided into three groups dependent upon their clinical presentation and need for respiratory support: Group I patients had severe pulmonary dysfunction-tachypnea, dyspnea, arterial PO2 less than or equal to 60 torr, arterial PCO2 greater than or equal to 50 torr or shunt fraction greater than or equal to 25%. Group II patients had no pulmonary dysfunction but did require temporary respirator support for an associated injury. Group III patients had no pulmonary dysfunction. Thirteen patients were assigned to Group I. They required respiratory support for an average of 10.5 days; 11 of the 13 had complications, and there were two deaths in this group resulting from a combination of respiratory failure and myocardial infarction. Seven patients were assigned to Group II. six patients were extubated immediately postoperatively; one patient with a head injury was hyperventilated for 48 hours to reduce intracranial pressure and then extubated. Sixteen patients were assigned to Group III. Fifteen required no ventilatory support. One 83-year-old man developed pneumonia and was mechanically ventilated for 31 days. Early effective pain control and chest physiotherapy were critical to success and were used in all patients. Increase in respiratory rate, fall in tidal volume or vital capacity, and increased pain were used as criteria for administration of analgesia. Nonventilatory therapy of flail chest reduces morbidity, mortality, and hospital cost.

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.

Liver is the largest organ and is located in the right upper quadrant of the abdominal cavity. Surgery for liver transplantation is performed through a large skin incision, which gives considerable pain post operatively. We experienced 10 cases of liver transplant, 3 cases used meperidine 0.5 mg/kg intramuscularly, 3 cases used epidural morphine analgesia, and for the remainder 4 cases, we used morphine 2-3 mg intravenously as needed. Liver transplantation is a major surgery. It attracts media for reporting. The hospital administrator realized its importance to the hospital. A 24 hours special nursing team was provided. Addition analgesic medication was given intravenously in a bolus dose of 2-3 mg of morphine. All patients were able to communicate freely with the nursing team. The communication between the patient and nursing team is free. No post-analgesic hypotension or dyspnea were noted. Patients in all three groups were equally satisfied with their analgesic therapy post-operatively. As all patients expect pain after surgery, they were satisfied when the pain was less than what they had anticipated. Blood gases analysis was however better in patients with epidural morphine analgesia.

A retrospective case note audit was conducted in order to determine the most prevalent symptoms in terminal dementia and to assess the palliation given. Seventeen case notes were audited. Pain and dyspnoea were the most common symptoms. The palliation and treatment of constipation and oral candidiasis was within current accepted practice. Palliation of other symptoms were inadequate compared to current accepted practice. There appears to be a reluctance to prescribe opiate analgesia, and when this was prescribed the doses were not modified to achieve full pain or symptomatic relief. Many patients were unable to take medication orally, but syringe drivers were not used. The conclusions include the need for education of both nursing and medical staff as to the current principles of palliative care.
