We examined the efficacy of the vertical infraclavicular block for plexus brachialis anaesthesia using a nerve stimulator after introducing the method (VIP1) and after three years of clinical experience (VIP2). In two prospective studies we compared the results with each other as well as with the efficacy of the axillary block (AX). At VIP1, we found a complete analgesia in 88% of the patients, whereas in 9% a supplementation was needed. In group AX the results were significantly worse (complete: 70%, supplementation: 24%; p < 0.001). No increase of the rate of efficacy could be found when having some clinical experience with the VIP (VIP2: complete 87%, supplement: 11%). In general, the results of the VIP depended on the motoric answer to the nerve stimulation. There were no complications of the VIP such as nerve lesions or pneumothorax. The VIP using a nerve stimulator is a simple, reliable and uncomplicated method for plexus-brachialis-anaesthesia, which is easy to learn.

Diagnostic and therapeutic potentials and our first two-year experience with video-assisted thoracic surgery (VATS) are reported. From May 1995 to April 1997, at the Department of Surgery, University Hospital Split, VATS approach was planned in 55 cases (recurrent pneumothorax in 23, tension pneumothorax in 1, traumatic effusion in 5, malignant metastatic lung tumor in 1, benignant lung tumor in 11, traumatic effusion in 5, suspected mediastinal lymph nodes in 4, long lasting unconfirmed pleural effusion in 9, foreign body in 1, mediastanal cyst in 1). Of these, 48 procedures (87.2%) were performed using VATS (diagnostic thoracoscopy in 12, wedge resection with or without pleural abrasion in 21, partial pleurectomy in 1, decortications in 3, mediastinal lymph nodes biopsy in 4, lung biopsy in 7). Seven patients (12.7%) underwent conventional posterolateral thoracotomy. Complications included persistent air leak in three patients, prolonged bleeding in one patient and supraventricular tachycardia in one patient. The mean duration of chest tube drainage after the procedure was 3.7 days (range 2 to 19 days), and mean hospital stay was 5.1 days (range 3 to 15 days). All patients received routine antimicrobial chemoprophylaxis with single-dose ceftriaxone 2 g intravenously immediately prior to the surgery, and average postoperative patient-controlled analgesia with buprenorphine 0.15 mg. We conclude that VATS is a very useful alternative to conventional thoracotomy in managing cases of exploration, recurrent spontaneous pneumothorax, benign pulmonary lesions, solitary pulmonary nodes, early decortications and different intrathoracic biopsies.

Laparoscopy employs highly technical equipment, and the surgeon needs special training in the technique. He should master in-depth knowledge of the use of optics, electrical principles, gas under pressure, and the physiologic changes that occur when carbon dioxide is placed in the abdominal cavity. Above all, the surgeon must adhere rigidly to guidelines for appropriate technique, and deviation will most assuredly result in complications and even death. General surgery application of laparoscopy followed a wealth of medical experience from gynecological laparoscopies, which declared the technique as safe, reduced hospital stay with little pain and disfigurement. Laparoscopic cholecystectomy started to enjoy ever increasing popularity. It retained the advantages of shorter hospital stay, more rapid return to normal activities, less pain, small incisions and less postoperative ileus compared with the traditional open cholecystectomy. Soon many procedures were done using this new technique in adults and children. Anesthesia for laparoscopy has been established with a broad usage of agents and techniques. General anesthesia using balanced anesthesia technique including intravenous induction agents like: thiopentone, propofol, etomidate, and inhalational agents like nitrous oxide, isoflurane, desflurane, has been reported. Variety of muscle relaxants including succinylcholine, mivacurium, atracurium, vecuronium aiming at rapid recovery and cardiovascular stability. Total intravenous anesthesia using agnets like propofol, midazolam and ketamine, alfentanil and vecuronium has been reported also for outpatient laparoscopy. Epidural anesthesia was considered as safe alternative to general anesthesia for outpatient laparoscopy without associated respiratory depression. As for pain relief, many methods have been used. The pain mechanism is variable and analgesia requirement is less than those of open surgery. Cited complications include pneumothorax, cardiovascular collapse, surgical emphysema and pneumo-peritoneum complications. Among the implication for anesthesia care, the importance of preoperative monitoring, careful positioning and observation during the insufflation of carbon dioxide. The drive to have short term admission to hospital would make it imperative to use short acting rapidly eliminated anesthetic drugs, avoidance of vomiting and pain by proper use of modern anti-emetics and NSAID to help in avoidance of narcotics or reduction of the requirement.

We report our first experience in surgical treatment of recurrent spontaneous pneumothorax using video-assisted thoracic surgery (VATS). From May 1995 to April 1998, 38 cases of recurrent spontaneous pneumothorax were treated using the VATS approach. All patients were previously treated by other methods (conservative, thoracocentesis, chest-tube drainage). We successfully managed VATS procedure in all our patients (wedge resection 28, bullectomy 1, partial pleurectomy 2, pleural abrasions 36). Complications include persistent air leak (4), prolonged bleeding (1) and supraventricular tachycardia (1). The mean duration of chest drainage was 3.9 days (range 3 to 15 days). All patients received antimicrobial chemoprophylaxis with single-dose of 2 g Ceftriaxone intravenously prior to surgery and average postoperative patient-controlled analgesia with 0.15 mg of buprenorphin. Utilisation resource analysis showed great advantage in favour of VATS procedure compared to retrospectively analysed thoracotomied patients. We conclude that VATS is very useful alternative to conventional thoracotomy in managing cases of recurrent spontaneous pneumothorax.

We report our initial experience with thoracoscopic surgery in the treatment of spontaneous pneumothorax in 14 patients, mean age 30.7 years. 7 were operated following 2 episodes of spontaneous pneumothorax, 6 after their first episode, and 1 after multiple episodes. All underwent bleb resection, pleurodesis and tube thoracostomy; in 1 we converted to a limited thoracotomy (93% success rate). Only oral analgesia was required for postoperative pain control and patients were discharged 2.6 days after surgery, on average. The apparent superiority of thoracoscopic over conventional, even limited, thoracotomy seems to justify such therapy even during the first episode.

Classical supraclavicular brachial plexus block was used as the sole anaesthetic technique in 200 children aged between 5 and 12 years undergoing closed reduction of arm fractures. The local anaesthetic used was lidocaine 1.5% with epinephrine. The block was graded as satisfactory if surgical manipulation could be performed without discomfort and unsatisfactory if general anaesthesia had to be given. In 182 children, the procedure was carried out under the block alone, whereas the remaining 18 patients required general anaesthesia. The mean (SD) time required for performing the block was 9.1 (3.7) min and the mean (SD) time to sensory blockade was 8.3 (2.3) min. The mean duration of analgesia was approximately 3.5 h. There were few complications, with no incidence of pneumothorax in any patient. The acceptability of the block by the children and the parents was 72 and 85%, respectively. The classical supraclavicular brachial plexus block was found to be acceptable, effective and with a good success rate.

Consecutive 25 patients (M/F:18/7) underwent video-assisted thoracoscopic surgery (VATS) for various chest illnesses. These included nine cases of pneumothorax, three cases of pericardial effusion, three cases of pleural effusion, four cases of lung lesion requiring either incisional or excisional biopsy, two cases of empyema, one case of traumatic haemothorax, and three cases of mediastinal lesion. The mean age was 36.2 years (range 19-78 years). A total of forty-three procedures were performed. The mean durations of intrapleural chest-tube requirement and hospitalisation following VATS alone were 4.5 days (range: 0-13 days) and 8.3 days (range: 2-25 days) respectively. No intraoperative complication and VATS procedure-related mortality reported. Apart from simple analgesics such as paracetamol or tramadolol, no opiate analgesia was given to patients undergoing only VATS. The results support that VATS is a safe and effective procedure in the management of pulmonary, mediastinal, pericardial and pleural diseases and the treatment of persistent and recurrent spontaneous pneumothorax.

Cryoanalgesia (the use of cold to provide anesthesia or analgesia) is the oldest anesthetic and analgesic still in current clinical use. Its intraoperative use in providing postoperative analgesia for acute thoracic pain problems via an open thoracotomy is well described. The long-term efficacy of cryoanalgesia for the management of chronic thoracic pain due to intercostal neuralgia is less clear. We retrospectively examined the medical records of patients who received percutaneous cryoanalgesia following successful intercostal nerve blockade for chronic chest pain. Sixty percent of the patients (N = 43) reported significant pain relief immediately following their procedure. Three months following cryoanalgesia, 50% continued to report significant pain relief. There were no reports of neuritis or neuroma formation and only three patients had a pneumothorax. This work provides evidence that cryoanalgesia is a safe and efficacious method of providing analgesia for chronic thoracic pain due to intercostal neuralgia.

Nuss described a minimally invasive technique for correcting pectus excavatum in children. A curved stainless-steel bar is inserted behind the sternum through the chest cavity with the convex surface face down, then rotated 180 degrees to elevate the sternum and correct the deformity. The procedure gained wide acceptance in children. The purpose of this study was to determine if the procedure is effective in adults. Only patients with symptoms limiting lifestyle, chest wall indices higher than 3.25, and demonstrable cardiac compression on echocardiography were accepted. Between April 1998 and January 2001, 14 adults aged 19 to 46 underwent assessment for the Nuss minimally invasive technique for correction of pectus excavatum. Eight patients, 19 to 32 years of age, met the stated criteria for acceptance. The comorbidities were 2 asymmetrical deformities, 2 scolioses, 1 previous pectus repair, and 1 previous breast augmentation. The patients were informed of the benefits and disadvantages of both the Ravitch and the Nuss procedures. All patients except the first had talked to one or more adults who previously had the procedure. Follow-up was 7 to 37 months (mean 22.1 months). Four patients have had their bars removed and maintained correction. Success of the operation was based on relief of cardiac compression, alleviation of symptoms, and adequate pain control. Operating time was 1 to 2:05 hours (mean 1:32 hours). Complications were pneumothorax in one patient, urinary retention in 2, and left lower lobe atelectasis in 5. Complications did not prolong hospitalization. Postoperative epidural analgesia was discontinued after 2 to 4 days (mean 2.8 days). Average daily pain scores were between 1.6 and 3.7 on a scale of 0 to 10. Hospital stay was 3 to 5 days (mean 4 days). Relief of symptoms and increase in activity were obtained in all patients. Relief of cardiac compression was demonstrated in the 6 patients who have had postoperative echocardiograms. Patients returned to normal activity 2 to 4 weeks postoperatively (mean 2.3 weeks). Duration of pain medicine was 2 to 4 weeks in 6 patients and 2 and 4 months for the other 2 (mean 5.5 weeks). There were 2 late complications related to the bar, but without loss of correction. The early experience with the Nuss minimally invasive pectus excavatum repair in adults is encouraging. The procedure is effective for correcting pectus excavatum in selected patients. Early results are dependent upon adequate bar stabilization and pain control. The long-term results in adults are unknown.

A parturient with idiopathic thrombocytopenia received labor analgesia with bilateral paravertebral blocks, because epidural analgesia was contraindicated due to her low platelet count (69,000.microliter-1) even after intravenous administration of freeze-dried sulfonated human normal globulin (400 mg.kg-1.day-1) and transfusion of platelet (20 units.day-1). In spite of predonisolone (1 mg.kg-1.day-1) p.o., her platelet counts could not increase at early gestation period. Prior to the induction of the labor, two catheters were inserted into T 11 bilateral paravertebral spaces, then 0.2% ropivacaine 10 ml was administered in each side, followed by the infusion at 5 ml.hr-1 each for the management of first stage of labor pain. Labor was induced with oxytocin infusion at 2.5-5.0 mU.min-1. As she requested additional analgesia in the second stage of labor, fentanyl 50 micrograms was administered twice intravenously. The labor course was uneventful with adequate analgesia, and the neonate (2,826 g) was vigorous with Apgar scores 9/10. Complications associated with this block such as hypotension, vascular or pleural punctures and pneumothorax were not seen. Bilateral paravertebral blocks may provide adequate analgesia as an alternative method for labor analgesia in a parturient with thrombocytopenia when conventional epidural analgesia is contraindicated.
