Between June 1974 and January 1976, 50 patients with metastatic non-seminometous testicular carcinoma were treated with the VAB II protocol. The induction phase consisted of vinblastine (0.4 mg/kg) and actinomycin D (0.02 mg/kg) on day 1. Bleomycin (0.5 mg/kg) was given by continuous infusion for 7 days, and cis-diammine-dichloroplatinum (II) (DDP) (1 mg/kg) was given on day 8. A weekly maintenance of vinblastine and bleomycin, with actinomycin D and DDP on a rotating schedule was given followed by vinblastine, actinomycin D and chlorambucil every 3--4 weeks. Therapy was discontinued after 30--36 months of treatment in the face of continued remission. The response rate was 50% CR, 34% PR with 60% CR and 36% PR in previously untreated patients. Second-look surgery and excision of residual lesions was performed in selected cases. Alopecia, mucositis, nausea, and vomiting were universal. One patient died in the postsurgical period of toxicity from the combination of bleomycin and high concentrations of oxygen. There were seven instances of allergic reactions to DDP. Eleven of 25 complete responders and 4 partial or minor responders who underwent excision of stable disease remain alive from 19 to 35 months following start of therapy, 12 of them without evidence of disease.

Eight sailors on board the Asiafreighter were exposed to arsine that had escaped from a cylinder in the cargo hold. Four suffered severe toxicity and within a few hours had developed fever, weakness, nausea, vomiting, diarrhoea, abdominal pain, and haemoglobinuria. These patients had pronounced intravascular haemolysis, which in one patient was complete. This patient was also stuporose and anoxic, a condition attributed to failure of oxygen transport and sludging of red cell debris in the cerebral and pulmonary circulations, but he regained a normal level of consciousness after exchange transfusion. Evidence of marrow depression was present: the reticulocyte response to the haemolysis was poor and there was a thrombocytopenia. All four patients developed renal failure, one being totally anuric for five weeks. Two patients developed peripheral neuropathy, and one was still severely disabled six months after the incident. The other four patients had a similar, though less severe, illness.

Most of the previous literature concerning otologic problems in compressed gas environments has emphasized middle ear barotrauma. With recent increases in commercial, military, and sport diving to deeper depths, inner ear disturbances during these exposures have been noted more frequently. Studies of inner ear physiology and pathology during diving indicate that the causes and treatment of these problems differ depending upon the phase and type of diving. Humans exposed to simulated depths of up to 305 meters without barotrauma or decompression sickness develop transient, conductive hearing losses with no audiometric evidence of cochlear dysfunction. Transient vertigo and nystagmus during diving have been noted with caloric stimulation, resulting from the unequal entry of cold water into the external auditory canals, and with asymmetric middle ear pressure equilibration during ascent and descent (alternobaric vertigo). Equilibrium disturbances noted with nitrogen narcosis, oxygen toxicity, hypercarbia, or hypoxia appear primarily related to the effects of these conditions upon the central nervous system and not to specific vestibular end-organ dysfunction. Compression of humans in helium-oxygen at depths greater than 152.4 meters results in transient symptoms of tremor, dizziness, and nausea plus decrements in postural equilibrium and psychomotor performance, the high pressure nervous syndrome. Vestibular function studies during these conditions indicate that these problems are due to central dysfunction and not to vestibular end-organ dysfunction. Persistent inner ear injuries have been noted during several phases of diving: 1) Such injuries during compression (inner ear barotrauma) have been related to round window ruptures occurring with straining, or a Valsalva's maneuver during inadequate middle ear pressure equilibration. Divers who develop cochlear and/or vestibular symptoms during shallow diving in which decompression sickness is unlikely or during compression in deeper diving, should be placed on bed rest with head elevation and avoidance of maneuvers which result in increased cerebrospinal fluid and intralabyrinthine pressure. With no improvement in symptoms after 48 hours, exploratory tympanotomy and repair of a possible labyrinthine window fistula should be considered. Recompression therapy is contraindicated in these cases...

Acute dapsone poisoning is rare and such cases are either accidental or suicidal. Though accidental DDS poisoning are reported in children, the same is fairly uncommon in adults. Only 2 such cases are reported in India literature. We here report 4 cases of fatal sucidial DDS poisoning in adults resulting death in 3 cases. The reported acute symptoms include nausea, vomiting, hyperexcitability followed by depression, Carpopedal spasm or convulsions. The most marked signs are dyspnoea and cyanosis. The symptoms are due to methaemoglobinaemia, and or sulphaemoglobinaemia. Normally dapsone induces red cell haemolysis and even with small therapeutic doses of 25-100 mg per day, and in toxic doses reduces the oxygen carrying capacity of blood and damages the red cells making them more vulnerable for haemolysis. The peculiarity of the presentation in this series are manifestation of severe haemorrhagic episode in one case and progressive jaundice in another besides cyanosis. None of the cases had carpopedal spasm or convulsion. Out of four cases three died inspite of intensive care, intravenous vitamin C, exchange transfusion (2 cases) and other supportive measures. Intravenous methylene blue could not be used in these cases due to non-availability.

In 10 healthy male volunteers breathing 100% oxygen, we determined the effect of four intravenous dose levels of fentanyl (0.0015, 0.003, 0.006 and 0.009 mg/kg) and two of fentanyl plus droperidol (i.e., Innovar, 0.003 and 0.006 mg/kg of fentanyl with 2.5 mg of droperidol for each 0.05 mg of fentanyl) on PECO2 and the slope of the ventilatory response to imposed increases in PECO2. All doses of fentanyl and fentanyl plus droperidol depressed the slope and shifted the curve to the right. Depression was dose related and was maximum 5 minutes after administration. The slope returned to control by 2 hours postinjection even at the highest narcotic dose. However, the rightward shift of the CO2 response curve require 4 hours to return to control. Droperidol added to fentanyl did not increase or prolong the respiratory depression seen with fentanyl alone at equivalent dose levels. Nausea and emesis occurred more frequently with fentanyl alone and orthostatic hypotension occurred more frequently with droperidol plus fentanyl. Dysphoria was a prominent consequence of fentanyl plus droperidol administration.

A unique opportunity was presented to observe the potentially toxic effects of an acute exposure to the vapors of petroleum naphtha distillate on a relatively large number of individuals. The immediate manifestation in all was dyspnea. The action on motor vehicle combustion suggested that some of this could have been due to oxygen deprivation; however, all individuals were dyspneic for several minutes after exposure. A few were cyanotic for several minutes after exposure. All were excited. Tremulousness and mild nausea followed the initial symptoms but were of brief duration. One individual manifested numerous premature ventricular contractions. Since his exposure was brief and since none of the others showed similar findings, it is unlikely that the exposure was causal. The central nervous system depression described in acute exposure cases of the intact (not distillate) petroleum naphtha fumes was not observed in any of this series. There were no delayed manifestations or complications.

Five subjects were compressed to 1000 ft (31 ATA) for 2 h breathing 3.2 ATA nitrogen, 0.5 ATA oxygen, and the remainder helium. The compression took 33 min with a 10-s stage at 50 ft (2.5 ATA), 1 MIN AT 320 FT (10.7 ATA), and 2 min at 700 ft (22 ATA). Hypothetically, this 1:10 ratio for nitrogen-helium partial pressures should induce neither nitrogen narcosis nor the High Pressure Nervous Syndrome (HPNS). Tests, therefore, were made during the experiment of postural tremor, spontaneous electroencephalogram, psychomotor and intellectual activities, and subjective sensations. One diver worked underwater for 40 min on a simulated engineering assembly while breathing with a closed-circuit breathing apparatus and wearing a battery-heated suit in water at 56 degrees F. Decompression was in 4 d using 0.8 ATA oxygen and helium. The performance tests indicated no narcosis and little or no signs of HPNS. No tremor or EEG changes were seen. The "wet" diver reported sensations of mild euphoria but the other four reported no difficulties. No nausea or dizziness of HPNS was reported. It is concluded that use of a ratio of 1:10::N2:He is effective in the control of narcosis and HPNS during rapid compression to 1000 ft (31 ATA).

This prospective study was conducted to determine the sedative effects of IV ketamine and fentanyl on vital signs and behavior. Twenty-seven children, classified as ASA I, with a mean age of 34 months, were studied. The dosages of IV ketamine and fentanyl given were 0.5 mg/kg and 0.5 mcg/kg, respectively, approximately every 15-20 min. The pulse rate averaged 125 throughout the case. Blood pressure averaged 112/64. The respiration rate averaged 22 breaths per min. Mean behavior composite scores were 1.9 at the initial examination and 3.3 during treatment. One child vomited during treatment. Post-treatment complications were discomfort in 19% (5), nausea in 22% (6), and vomiting in 15% (4) of the patients. We concluded that IV sedation of precooperative healthy pediatric patients with ketamine, fentanyl, and nitrous oxide/oxygen appears to be a safe and effective sedation modality with minimal side effects when administered and monitored by a qualified anesthetist, offering the practitioner an alternative to general anesthesia.

Epidural administration of an opioid analgesic by means of a patient-controlled analgesia (PCA) system was compared with conventional intravenous PCA for pain relief after cesarean delivery. One hundred seventeen healthy women were randomly assigned to receive hydromorphone either intravenously (IV-PCA) or epidurally (EPI-PCA) after cesarean delivery with epidural bupivacaine for operative anesthesia. The hydromorphone requirements were 3.4 and 4.2 times more in the IV-PCA group on the first (P less than 0.01) and second (P less than 0.01) postoperative days, respectively. The mean number (+/- SD) of PCA demands during the first 24 h after the operation was 105 (+/- 88) for the IV-PCA group and 33 (+/- 48) for the EPI-PCA group (P less than 0.01). This difference was also significant 24-48 h after surgery. Although the EPI-PCA group utilized significantly less opioid medication, pain and sedation scores were similar in the two treatment groups; however, a significantly larger percentage of patients in the IV-PCA group (46% vs 22%) stated that they felt drowsy during the first postoperative day. Pruritus was reported more frequently in the EPI-PCA (67%) than in the IV-PCA (33%) group. Nausea was experienced by only 10% of patients in the IV-PCA and 6% in the EPI-PCA group. There was no evidence of postoperative respiratory depression, with minimal oxygen saturation values of 93% (+/- 3%) and 94% (+/- 1%) in the IV-PCA and EPI-PCA groups, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)

The prophylactic antiemetic efficacy of ondansetron was evaluated in a randomized, double-blind comparison with droperidol and metoclopramide in 66 patients undergoing general anesthesia for dilatation and curettage. Ten minutes before induction of anesthesia, 22 patients received a single intravenous dose of 8 mg of ondansetron, 22 others received 1.25 mg of droperidol, and the remaining 22 received 10 mg of metoclopramide. Anesthesia was induced with 3.3-5 mg/kg of intravenous thiopental and maintained with 65% nitrous oxide in oxygen and 2%-3% enflurane. Postoperatively, the incidence of vomiting was 13% with ondansetron, 45% with droperidol, and 54% with metoclopramide (P less than 0.05; overall chi 2 test). There was no statistically significant difference in the incidence of nausea among the groups. Postoperative sedation and well-being scores were not significantly different among the groups. We conclude that preoperative prophylactic administration of ondansetron is superior to droperidol or metoclopramide in the prevention of emetic sequelae after general anesthesia for dilatation and curettage.
