Sixty patients undergoing shock wave lithotripsy of gallbladder stones (ESWL) were randomly assigned to receive alfentanil either by infusion controlled by the attending anesthesiologist (standard treatment group, n = 31) or by analgesia controlled by the patient (PCA group, n = 29). Patients using PCA were allowed to self-administer 0.25 mg of alfentanil i.v. every minute as required. Data collected during treatment included the total dose of drug required, transcutaneous pCO2 values, verbal pain and sedation scores, visual analogue scale (VAS) patient satisfaction scores, and the incidence of nausea or vomiting. PCA patients used less alfentanil than the standard treatment group (PCA group: 12.8 micrograms/kg; standard treatment group: 44.3 micrograms/kg; mean values, P = 0.0001), tolerated significantly higher pain intensities and self-administered the narcotic only to moderate levels of pain but not to pronounced analgesia. Standard treatment patients reported lower levels of pain, were more sedated (P less than 0.05) and showed significantly higher transcutaneous pCO2 values. There was a trend towards a lower incidence of nausea or vomiting in PCA patients without reaching statistical significance. No significant difference with regard to patient satisfaction with pain relief could be demonstrated. Self-administered alfentanil during ESWL of gallbladder stones provided adequate analgesia with minimal side effects and high patient satisfaction. ESWL may represent a new and useful indication for PCA.

Patient-controlled analgesia (PCA, intravenous self-application of narcotics) was studied during the early postoperative period. Subjects were 40 ASA I-III patients recovering from elective major and minor surgery (20 each having undergone abdominal or orthopedic operations). Whenever the patients required pain relief, piritramid demand doses of 2.0 mg were given via the hand-button of a microprocessor-controlled injection pump (On-Demand Analgesia Computer, ODAC). Hourly maximum dose was set to 15 mg with a pump refractory time of 1 minute between valid demands. A continuous low-dose piritramid infusion (0.24 mg/h) was additionally administered in order to prevent catheter obstruction. Duration of the PCA period was 19.7 +/- 6.5 hours (mean +/- SD). During this time, 17.1 +/- 13.8 demands per patient were recorded resulting in mean individual piritramid consumptions of 30.4 +/- 28.1 micrograms/kg/h. Self-administration was characterized by considerable intra- and interindividual variability. Following abdominal surgery, slightly more piritramid was needed compared with orthopedic patients, although less pain relief was achieved in the former group. The same proved to be true for a comparison between the sexes, males requiring significantly more piritramide for less pain relief than females (p = 0.05). Over-all efficacy and patient acceptance proved to be excellent. Effectiveness of PCA was judged superior by about 73% of patients when compared with previously experienced conventional postoperative analgesia. Side effects (sweating, nausea, emesis) occurred in about 20% but were usually of minor intensity. No serious circulatory or respiratory problems were observed during the PCA period. Patient-controlled analgesia is discussed as a promising concept for the treatment of acute pain and for clinical pain research.

A successful case undergoing the ECA-PCA bypass operation with the use of an interposition saphenous venous graft for vertebrobasilar progressing stroke was reported and details of the operative techniques were described. A 40-year-old man was admitted because of confused mental state following sudden onset of headache, vomiting, vertigo, and ataxic gait. Neurological examinations revealed he was confused and restless, and left-sided Weber's syndrome, bulbar palsy and dysphasia were noticed. CT scan showed multiple small low density areas with no enhancement scattering in both occipital lobes and cerebellar hemispheres. Angiographical studies showed that the left vertebral artery was occluded at the vertebrobasilar junction and the right vertebral artery stenosed up to 90% or more at the branching site of the PICA. There was no visualization of the vertebrobasilar system through the right posterior communicating artery. The left posterior communicating artery was not examined. The patient was treated with Urokinase amounting to 740,000 units for ten days. Thirteen days later, however, he became progressively drowsy and he became unable to speak and swallow. Quadriparesis also appeared. Progressive deterioration of these brain stem ischemic symptoms was assumed to originate from critically lowered perfusion of the vertebrobasilar circulation. Therefore, the ECA-PCA anastomosis by means of a venous graft was carried out on the right side in expectation of the rapid restoration of the blood flow in the affected brain stem. A venous graft was chosen because it would carry larger amount of blood immediately after completing the bypass surgery than small calibered arterial graft such as a superficial temporal artery.(ABSTRACT TRUNCATED AT 250 WORDS)

Patient-controlled analgesia (PCA, intravenous self-application of narcotics) was studied during the early postoperative period. Subjects were 40 ASA I-III patients recovering from elective major and minor surgery (each 20 having undergone abdominal or orthopaedic operations). Pentazocine bolusses of each 8 mg were available via a hand-button whenever the patients felt pain relief necessary, and delivered by a microprocessor-controlled injection pump (On-Demand Analgesia Computer, ODAC). Hourly maximum dose was set to 60 mg with a pump refractory time of 1 min between valid demands. A continuous low-dose pentazocine infusion (1 mg/h) was additionally administered in order to prevent catheter obstruction. Duration of the PCA period was 20.3 +/- 5.9 h (mean, standard deviation). During this time, 20.0 +/- 12.7 demands per patient were recorded resulting in mean pentazocine consumption of 135.6 +/- 81.4 micrograms/kg/h. Self-administration was characterized by considerable intra- and interindividual variability. There were no statistically significant differences with regard of pentazocine consumption or pain relief between abdominal and orthopaedic patients, nor could any be demonstrated between the sexes. Similarly, no clear differences were found after various anaesthetic techniques (neuroleptanalgesia, halothane or spinal anaesthesia). Over-all efficacy and patient acceptance proved to be excellent. Effectiveness of PCA was judged superior by about 68% of patients when compared with previously experienced conventional postoperative analgesia. Side effects (nausea, emesis, sweating) occurred in about 10-18% but were usually of minor intensity. Circulatory or respiratory problems were not observed during the PCA period. Patient-controlled analgesia is discussed as a promising concept for the treatment of acute pain and clinical pain research.

A case of arterio-venous malformation (AVM) at the right parietal area in association with agenesis of the left internal carotid artery (ICA) is described. A 27-year-old male complained of severe headache and vomiting on September 27th in 1980. He lost his consciousness and became stuporous within several minutes after the ictus. He was then transferred to Kurume University Hospital. On admission, he was semicomatose, anisocoria and left hemiparesis marked in the lower limbs, and bilateral Babinski reflex were noted. A emergency CT scan revealed a round high density area suggesting intracerebral hematoma at the right parieto-occipital area. Right retrograde brachial angiography was then performed which showed a small AVM at the right parietal lobe mainly fed by the right posterior parietal arterial branch, and drained into the superior sagittal sinus, via the subcortial veins. Left MCA bilateral PCA and SCA also were demonstrated on the angiogram. The angiogram suggested on abnormality of the Willis ring. Emergency operation fro the small AVM associated with intracerebral hematoma was then performed. The AVM was sufficiently removed and approximately 80 gr. of intracerebral clots were also evacuated completely. Histological examination indicated a typical small AVM. The postoperative course was uneventful. Left CAG performed by seldinger method from the femoral artery after the operation showed no demonstration of the left ICA. the left common carotid artery was terminated as the external carotid artery without carotid bifurcation at the neck. The left ophthalmic artery was fed by the meningeal artery of the internal maxillary artery. Left vertebrobasilar system was normal. From an angiogram, the agenesis of the left ICA was most suspected. An agenesis of ICA was uncommon among the literature in which there was no case with this anomaly associated with cerebral AVM. The embryological consideration about this case was mainly discussed.

This is a retrospective study covering the ten-year period 1984-1993. Single shot spinal morphine (ITM) is compared with PCA nalbuphine for postoperative pain relief in children having abdominal or thoracic procedures. The records of 52 patients meeting selection criteria were examined. Nursing and physician notations were reviewed for hourly pain assessments, evidence of associated complications, respiratory depression, nausea and or vomiting, pruritus, and urinary retention. ITM provided significantly better pain relief (2.2 h in pain) during the first 24 h postoperatively than PCA nalbuphine (9.2 h in pain). With the exception of urinary retention which was significantly more frequent following ITM (58.6%) compared to PCA nalbuphine (8.7%), narcotic related complications were not different between the two groups. No difference in duration of hospital stay or ICU stay could be demonstrated. We conclude that ITM provides better pain relief, without more serious complications, than PCA nalbuphine. We recommend it as a safe, effective technique to treat postoperative pain in children following thoracic or upper abdominal procedures.

This is a report of unruptured aneurysms with occlusion of the basilar artery. A 61-year-old female was admitted to our hospital because of dysarthria and numbness of her left face. Angiography revealed occlusion of the basilar artery and severe arteriosclerosis of the bilateral cerebral carotid arteries. Pcom was not visualized on bilateral carotid angiogram. These neurological signs were considered to be derived from vertebrobasilar insufficiency by occlusion of the basilar artery. Right STA-SCA anatomosis was performed to prevent brain stem infarction. Postoperative angiography showed a good filling of both PCA and SCA by collateral circulation via a right STA and an unruptured basilar top aneurysm. Seven months after the bypass surgery, angiography disclosed that the basilar top aneurysm was visualized clearly, and its size was unchanged. The fact that there was no thrombus formation in the aneurysm was considered to be due to ticlopidine, and the hemodynamic changes after the bypass surgery were suspected to have increased the intraaneurysmal pressure. Therefore we performed neck clipping of the basilar top aneurysm by using a right pterional approach. Two years after the second operation, the patient complained of severe headache and vomiting. CT scan showed subarachnoid hemorrhage, and angiography demonstrated a newly developed aneurysm which might have ruptured on left internal carotid anterior choroidal artery bifurcation. Emergency neck clipping of the second aneurysm was performed, and the patient showed a good postoperative course. The newly developed second aneurysm might have been caused by severe arteriosclerosis and hypertension in addition to hemodynamic stress.

We compared the efficacy and safety of continuous epidural fentanyl infusion with intravenous morphine via a patient-controlled analgesia system (IV-PCA) in the management of postoperative pain after lumbar laminectomy. Twenty patients undergoing elective lumbar laminectomy were randomly allocated to one of two groups. The epidural group (n = 10) received an epidural fentanyl infusion (2 micrograms/mL at 4-10 mL/h) while the IV-PCA group (n = 10) received IV morphine through a PCA system. The general anesthetic technique was standardized. Visual analog pain scores were recorded at 12, 24, and 48 h after the operation. The amount of morphine (or its equivalent in fentanyl) used over the 48-h postoperative period was documented. The postoperative pain scores were significantly lower in the epidural group than in the IV-PCA group throughout the study period. The total consumption of morphine (or its fentanyl equivalent) over the 48-h period was significantly lower (P < 0.001) in the epidural group compared to the IV-PCA group. Although more patients in the IV-PCA group required urinary catheterization and had somnolence than the epidural group, there was no difference in the incidence of vomiting or pruritus. No patient developed respiratory depression or wound infection. We conclude that continuous epidural infusion of fentanyl is superior to IV-PCA morphine in the management of pain after lumbar laminectomy.

Forty children undergoing appendicectomy were allocated randomly to receive one of two PCA regimens with morphine. Group B10 received bolus doses of 10 micrograms kg-1 and group B20 received bolus doses of 20 micrograms kg-1. In both groups there was a lockout interval of 5 min and a background infusion of 4 micrograms kg-1 h-1. Group B20 self-administered considerably more morphine (P < 0.01) than group B10. There was no difference between the pain scores of the groups at rest. Group B20 had significantly (P < 0.05) smaller pain scores during movement than group B10 and the latter group suffered significantly (P < 0.01) more hypoxaemic episodes than group B20. There were no differences between the groups in the incidence of vomiting, excess sedation or the amount of time spent asleep at night.

The use of patient-controlled analgesia with alfentanil (PCA-alfentanil) as a form of pain relief for dressing procedures in patients during the acute phase of their burn injuries was investigated. Five ASA 1 and 2 patients with 10-30 per cent total body surface area (TBSA) thermal burns, had PCA-alfentanil for their dressing procedures after standard fluid resuscitation. One patient who did not receive a loading dose and a background infusion of alfentanil had unsatisfactory pain relief. Four patients had good pain relief after a loading dose of IV alfentanil 1 mg followed by a continuous background infusion of 200-800 micrograms/h. Demand dose ranged from 200 to 400 micrograms and lockout time ranged from 1 to 3 min. The total dose of alfentanil delivered ranged from 0.8 to 4.48 mg and duration of the dressings ranged from 30 to 60 min. All patients were mildly sedated, calm, communicative and cooperative during dressing procedures. None of them experienced hypotension or respiratory depression. One patient experienced nausea but no vomiting, no other adverse effects of alfentanil were noted. From the pilot study, PCA-alfentanil may be an effective form of pain relief for dressing procedures in patients during their acute phase of burn injuries. The optimal PCA-alfentanil setting has yet to be determined.
