The aim of this study was to assess the value of peridural thoracic analgesia (ATP) to prevent pain observed during pleural symphysis with tetracycline (STP) for pneumothorax (PNO). 12 patients (age 27 +/- 6 years) having a spontaneous PNO benefited from 13 SPT (1 gm, tetracycline diluted in 60 cc of normal saline) under cover of an APT (at the D5-D6 level) with Fentanyl (0.1 mg) and Bupivacaine 0.5% adrenalin (1 mg/kg). The protocol was used on three successive days. Repeated determinations of blood bupivacaine levels were performed in 9 patients on the first day. No patient had an intolerable pain which required injection of parenteral morphine and/or an interruption of the protocol. For two patients (one of them having a right symphysis and then a left symphysis one month later) the treatment sessions to achieve a symphysis were totally painless. 10 patients experienced moderate pain, mainly on the first day, which was relieved by reinjection of peridural bupivacaine (25 mg) (n = 9) or by the parenteral injection of non morphine analgesia (n = 1). No patient had a respiratory depression, collapse or bradycardia. The blood bupivacaine levels were always significantly less than the toxic levels (1.6 mg). The results observed suggest that APT, (Fentanyl and Bupivacaine) is an effective method, non toxic and well tolerated for the prevention of intolerable pain which is seen in SPT for PNO.

Since the first paravertebral blockade was carried out by Sellheim in 1905, this method has proved effective for the isolated blockade of spinal nerves. The efficacy of preoperative intercostal blockade (ICB) in combination with neuroleptanalgesia (NLA) or Pentothal-pentazocine-N2O anesthesia (Pe-Pz) was studied (unilateral analgesia for cholecystectomy). Group 1: NLA; group 2: NLA with ICB; group 3: Pe-Pz; group 4: Pe-Pz with ICB. The analgesic requirement differed significantly between groups 1 (0.33 mg fentanyl) and 2 (0.15 mg fentanyl) and groups 3 (63.5 mg pentazocine) and 4 (31.5 mg pentazocine). There were also significant differences in circulatory responses. The maximum deviation from the initial value at the beginning of the operation in group 1 compared to group 2 was pulse rate + 28.7% vs + 2.4%, mean arterial pressure (Part) + 24.6% vs + 3.1%, and systolic pressure (Psyst) + 33% vs +/- 0%; group 3 compared to group 4: pulse rate + 16.4% vs + 3.2%, Part + 24.5% vs 0.0%, and Psyst + 26.5% vs + 196. The times of action of ICB extended from 7.54 h to 11.33 h for partial analgeisa, time to the first dose of analgesic from 12.3 h to 16.9 h (etidocaine 0.5% and 1% respectively without and with epinephrine). The mean blood levels after 100 mg bupivacaine-CO2 rose to 1.16 micrograms/ml after 5 min and reached a maximum after 15 min (1.29 micrograms/ml) as compared to 0.98 micrograms/ml after addition of ornithine-vasopressin. These values are very much higher than those after the use of bupivacaine-HCl solution. Etidocaine and bupivacaine-HCl have comparable durations of analgesia. Toxicologically, both substances can be applied safely with consideration of all pharmacological data for ICB. Of a total of 3,485 intercostal blockades, 2,775 were applied perioperatively (pre- and postoperatively); 265 were carried out for trauma patients (rib fractures) and 445 for therapeutic indications (herpes zoster neuralgia, tumor pain, costovertebral pain). In 8 blocks 10% ammonium sulfate, in 4 blocks absolute alcohol, and in 19 blocks 5% phenol were used for neurolysis. In 2 cases a marginal pneumothorax was seen, which was resorbed spontaneously (0.06%). Altogether 16,270 single intercostal nerves were blocked. Single-session intercostal blockade can be combined as unilateral analgesia with general anesthesia. This combination is characterized by stable circulatory conditions with avoidance of hypertensive reactions. The long-lasting analgesia allows early mobilization and physiotherapy both postoperatively and posttraumatically in patients with unilateral thoracic and abdominal pain.(ABSTRACT TRUNCATED AT 400 WORDS)

Intrapleural marcaine has been described as an effective method of analgesia following upper abdominal and thoracic operations and is no longer regarded as experimental. We have shown that the same quality of analgesia can be achieved by injecting the drug through a catheter inserted intraoperatively through the surgical incision. In our method, applied in 9 cases, there is no risk of pneumothorax as a result of piercing the chest wall, since intraoperative placement of the intrapleural catheter is very easy. We therefore suggest it as the method of choice for postoperative analgesia in kidney operations. It is especially recommended in elderly patients with chronic pulmonary disease who do not tolerate narcotics well.

A modified technique of intercostal nerve blockade is described which is suitable for use in children. Ten patients received intercostal nerve blockade on a total of 29 occasions in order to provide analgesia following liver transplantation and to facilitate weaning from artificial ventilation of the lungs. The opioid requirement of patients who received intercostal nerve blockade was considerably lower than that of those who did not; 56% of the children who received intercostal nerve blockade required no additional analgesia. One child, the first to receive intercostal nerve blockade, developed a pneumothorax following the procedure. The technique has proved to be safe in skilled hands. It is an acceptable method of postoperative analgesia in children after liver transplantation and may be a useful technique in the management of other paediatric patients.

A randomised prospective study was conducted into 60 patients who had undergone thoracotomy for spontaneous pneumothorax or bronchial carcinoma. Pyrazolone was intramuscularly and intravenously injected for postoperative pain relief to some of these patients. Another group received morphine through an epidural catheter (TEA). Postoperative spirometric checks were made on the first, third, and fifth days from surgery. The degree of analgesia was measured by means of the Twycross method. The ventilation parameters recorded from patients with epidural morphine treatment were clearly better than those measured from patients who had received pyrazolone. The amount of pain relief reported by TEA patients were better than that recorded from the pyrazolone group.

Twenty-one patients who underwent elective cholecystectomy were studied with regard to the effect of intrapleural administration of bupivacaine-adrenaline solution on postoperative pain and ventilatory capacity. Administration of 10 or 20 ml of 2.5 mg/ml or 5 mg/ml bupivacaine solution resulted in complete analgesia in 143 of 159 administrations. Most patients experienced the maximal pain-relieving effect within 1-2 min and analgesia persisted as a rule for 3-5 h. Forced vital capacity and forced expiratory volume in 1 s increased after intrapleural analgesia on average by 56% and 46%, respectively, on the first postoperative day and by 35% and 51%, respectively, on the second day. There was no significant difference in the analgesic effect or in the effect on the ventilatory capacity between the 2.5 mg/ml or the 5 mg/ml solution, in either the 10 ml or the 20 ml dose. Placebo (NaCl) given intrapleurally had no effect on pain or on the ventilatory capacity. The plasma concentration of bupivacaine after intrapleural administration showed a wide interindividual variation, with considerably higher average values when the 5 mg/ml solution had been used than for the 2.5 mg/ml solution. Although no toxic effects were noted, a 2.5 mg/ml solution, which can be given in an initial dose of 20 ml and top-up doses of 10 ml at 3-6 h intervals, is recommended. In four patients minor pneumothorax developed when the catheter was introduced. The pneumothorax was easily evacuated, but underlines the need for great care when introducing the catheter.

The provision of analgesia using continuous bilateral intercostal blockade was compared with that provided by conventional i.v. narcotics for the first 48 h after cardiac surgery. The subjective quality of analgesia was significantly superior with the regional technique. However, pulmonary function tests, gas exchange, lung volume, and radiological and clinical evidence of pulmonary complications were not improved. The failure to reduce morbidity and the potential for complications such as pneumothorax, makes it difficult to recommend the regional analgesia technique in this situation.

During a 2 year period nitrous oxide was used as a sole or supplementary analgesic during 173 vascular or interventional procedures including peripheral angiography and endourologic and endobiliary procedures. The decision to administer nitrous oxide to a given patient was a matter of physician preference. Patients with bowel obstruction, pneumothorax, or chronic obstructive pulmonary disease were excluded from this method of analgesia. The nitrous oxide was administered by a radiology nurse under the supervision of an attending radiologist. Nitrous oxide was used without premedication for 39 procedures and with premedication (usually meperidine 1 mg/kg, promethazine 0.3 mg/kg, or atropine 0.01 mg/kg) in 134 procedures. In 74% of nonpremedicated individuals analgesia was adequate with nitrous oxide alone; 26% required supplemental intravenous medication. In 61% of premedicated individuals pain relief was adequate with nitrous oxide; 39% required supplemental intravenous medication. Complications, including nausea, vomiting, and agitation, occurred in eight patients, but were minor and easily reversed by decreasing the concentration of nitrous oxide. Nasally administered nitrous oxide is a safe, easily used, and effective analgesic.

For replantation surgery, continuous brachial plexus block was employed using supraclavicular or axillary approach. Of a total of fifty blocks, forty-seven (94%) gave adequate surgical analgesia throughout the operations. No serious complication appeared in this series. Pneumothorax was detected in one supraclavicular block, but no surgical drainage was required. One patient had paraesthesia in the blocked arm, but it subsided within a month. No toxic reaction was recognised in spite of high dose of anaesthetic agents. Thus continuous brachial plexus block has been ascertained to be safe, reliable, and useful for the replantation and other prolonged operations in the upper extremity.

The failure rate and complications were studied prospectively in 367 paediatric and adult patients who had received a thoracic or lumbar paravertebral block. The overall failure rate was 10.1%; adults 10.7%; children 6.2%. The frequency of complications were: hypotension: 4.6%; vascular puncture: 3.8%; pleural puncture: 1.1%; pneumothorax: 0.5%. Since these results are similar to those found with alternative methods, e.g. epidural, intrapleural and intercostal blocks, paravertebral block can be recommended as an effective, safe technique for unilateral analgesia in both adults and children.
