We compared analgesia and sedation provided by one of four different opioids in combination with midazolam during gastrointestinal endoscopy. Patients were given 1-3 mg midazolam and meperidine 50-100 mg, fentanyl 50-100 micrograms, sufentanil 5-10 micrograms, or alfentanil 150-300 micrograms, plus additional opioid and/or midazolam if needed. No untoward effects (i.e., O2 saturation < 85%, nausea, vomiting, severe bradycardia) occurred. Sedation and analgesia were comparable in the upper gastrointestinal groups. The number of patients with amnesia for the examination was highest in the meperidine group. Recovery time generally was shorter with alfentanil and sufentanil. Recovery time of the lower gastrointestinal patients was significantly longer in the meperidine group than in the other groups; analgesia scores for sufentanil were significantly lower than for meperidine. Sedation scores for these patients were highest in the meperidine group. The number of patients given meperidine who were amnesic was significantly greater than for the other opioids. Meperidine was better than the other opioids with regard to patient comfort and amnesia during colonoscopy.

Sedation for genital examination in suspected sexual abuse is seldom discussed. The cases are presented of three children in whom genital examination was facilitated by ketamine sedation; these children could not be examined under any other circumstances. Ketamine provides safe, effective sedation, analgesia, and amnesia in an ambulatory setting. Its use should be considered in selected patients.

The postoperative analgesia afforded after colonic surgery by IV opioid, clonidine and lignocaine given intra- and postoperatively was evaluated. In a double-blind randomised trial, 80 male patients scheduled for colonic resection under general anaesthesia received fentanyl 5 micrograms.kg-1 at induction and another 4 micrograms.kg-1 before skin incision (group A) or fentanyl (same dose) plus clonidine 4 micrograms.kg-1 in 20 min + 2 micrograms.kg-1.h-1 (group B, C) or fentanyl plus clonidine (same dosage) plus lignocaine 2 mg.kg-1 before skin incision, repeated before peritoneal incision and retractor placement (group D). In the four groups, intraoperative boluses of fentanyl 2 micrograms.kg-1 were given in response to the painful stimulation of the procedure. Postoperative pain was managed with PCA delivering 2 mg morphine per request in group A, 1.5 mg morphine in group B, 1.5 mg morphine + 15 micrograms clonidine in group C and 1.2 mg morphine + 15 micrograms clonidine + 23 mg lignocaine in group D. Postoperative analgesia was assessed by recording the analgesic demands (met and unmet) and the dose of morphine delivered at 6, 12, 18, 24, 36 hours. Side-effects, pain and sedation analogue scores were also recorded. Analgesic demands and delivered morphine dose were reduced, at any time interval considered, in groups B, C, D, compared with A (P < 0.001). No differences were noted between the group B, C, D. Pain analogue scores were better in groups B, C, D compared with group A (P < 0.001). Sedation and side-effects were not increased in groups B, C, D.(ABSTRACT TRUNCATED AT 250 WORDS)

We have studied 42 healthy parturients with singleton vertex pregnancies, who were in the first stage of labour and requesting extradural analgesia. They were allocated randomly in a double-blind fashion to receive either 0.125% bupivacaine plain or 0.125% bupivacaine with clonidine 120 micrograms. Efficacy of analgesia was evaluated using linear visual analogue scoring (VAS), sensory block was assessed using bilateral pinprick in the mid-clavicular line and sedation scored on a five-point scale. Maternal and fetal cardiovascular variables were measured every 2 min for 20 min, at 30 min and subsequently at 15-min intervals. The reduction in VAS was greater at all times in the bupivacaine-clonidine group (P < 0.01). The median (range) duration of analgesia was greater in the bupivacaine-clonidine group (114.5 (30-243) min) compared with the bupivacaine group (53 (30-100) min) (P < 0.001). Analgesia was associated with a reduction in arterial pressure in both groups, but there were no between-group differences. Maternal heart rate was less than baseline values at 30-90 min in the bupivacaine-clonidine group only. Sedation was greater in the bupivacaine-clonidine group, especially from 15 to 45 min (P < 0.01). There were no differences in fetal heart rate, mode of delivery or Apgar scores between the two groups.

Sixty children (7 months-20 yr; mean 6.5 yr, median 7-8 yr, mode 1-2 yr) undergoing major surgery received a balanced technique of general anaesthesia combined with bupivacaine as a single injection extradural or peripheral nerve block. Postoperative analgesia consisted of a subcutaneous infusion of morphine 1 mg kg-1 body weight in 20 ml of normal saline [corrected] at a rate of 0.3-0.5 ml h-1, controlled by the nursing staff in the surgical ward. Monitoring included SpO2, pain, sedation and nausea/vomiting scores. Infusions were used for a mean of 38.8 h (range 17-80 h). Ninety-seven percent of recordings of SpO2 were greater than 94% and only one recording in 2361 was less than 90%. Ninety-four percent of pain scores indicated either no pain or slight pain; 1% indicated severe pain. On the order of the medical staff, seven children had the rate of infusion of morphine increased to 0.6 ml h-1 [corrected] because of high pain scores. Sedation scores compatible with children being either awake or asleep but rousable by speech alone were recorded on 99.7% of occasions. No child at any time was unrousable. Of 1248 nausea/vomiting scores, only 2.8% indicated the presence of these side effects; in only two children were they thought to be troublesome. As a result of this audit, nursing staff have been permitted to increase the rate of infusion of morphine to 0.6 ml h-1 [corrected] if required.

Sedation and analgesia are essential components of the ED management of pediatric patients. Used appropriately, there are a number of medications and techniques that can be used safely in the emergency care of infants and children. Emergency physicians should be competent in the use of multiple sedatives and analgesics. Adequate equipment and monitoring, staff training, discharge instructions and continuous quality management should be an integral part of the ED use of these agents.

The caudal border of the last rib was used as a reliable point of orientation while performing paravertebral thoracolumbar anaesthesia (PTLA) on 10 horses undergoing standing flank laparotomy. The local anaesthetic in all horses was 2% lidocaine. The PTLA procedure was completed in 9.8 +/- 1.8 mins (mean +/- sd). Sedation was provided by a combination of intravenous morphine with xylazine or detomidine. Overall analgesia, provided by the combination of PTLA and sedation, was rated as excellent in 2 horses and good in 6 horses. In the remaining 2 horses, overall analgesia was rated as fair because of incomplete analgesia at the ventral portion of the incision. Total time, from start of PTLA to end of surgery was 143.5 +/- 24.2 mins. Five horses responded mildly to suturing of the ventral portion of the incision. Apart from 1 horse which developed transient, unilateral hindlimb weakness intraoperatively, no other complications were noticed. We conclude that PTLA can easily be performed in the horse and, combined with systemic sedation, is an effective and safe method of providing analgesia for standing flank laparotomy.

Detomidine (Domosedan) was administered to four groups of donkeys, using four different dosages (5, 10, 20 and 40 micrograms/kg bwt) intravenously. The drug provided adequate sedation at dosages of 5 and 10 micrograms/kg bwt. Sedation deepened only slightly by increasing the dose. Analgesia was considered good with a dose of 20 micrograms/kg, and 40 micrograms/kg provided a deep analgesia associated with a longer duration. No significant changes had been observed in haematocrit (PCV), haemoglobin content (Hb %), total red and white cell counts and differential leucocytic counts. It was concluded that detomidine is a valuable sedative and analgesic drug to be used in donkeys without any serious implications.

Six beagle dogs were treated with xylazine hydrochloride (1 mg/kg i.m.). The plasma xylazine concentration was measured by HPLC. Additionally, clinical effects were registered (cardiac rate, respiratory activity, electrocardiogram, body temperature, motoric activity, attention, analgesia). Maximum plasma concentrations were measured after 15 minutes (476 ng/ml). The plasma half-life was 24 minutes. Sedation was registered over one hour (xylazine concentration of more than 150 ng/ml). Within the first 30 minutes after treatment (xylazine concentration of more than 300 ng/ml), a low-grade analgesia was observed. In contrast, cardiac and respiratoric depression and also significantly diminished body temperature were registered over 2 to 3 hours.

Seventy-two healthy dogs required sedation and analgesia for a variety of procedures causing discomfort or pain. They were treated either with the alpha 2-agonist medetomidine at 40 micrograms/kg (15 intravenously and 17 intramuscularly), or 80 micrograms/kg (15 intravenously and 15 intramuscularly) or with xylazine plus l-methadone (1.0 mg)(10 intravenously). The levels of sedation, analgesia and safety were compared clinically and by measurements of the effects on the electrocardiogram (ECG) and blood gases, body temperature, haematology and clinical chemistry. Sedation was achieved reliably with both medetomidine and xylazine plus l-methadone but its onset, depth and duration were influenced by the dose and route of administration. In the medetomidine-treated dogs, intravenous administration resulted in more rapid sedation and the effects of the higher dose were deeper and longer lasting. The small dogs receiving 40 micrograms/kg may have been underdosed. The initial analgesic effects in response to a pin prick to the body surface were sufficient and similar for both drugs, except for the intramuscular dose of 40 micrograms/kg medetomidine. Analgesia for the clinical procedures was less reliable with medetomidine and was not always adequate even at the high dose, but xylazine plus l-methadone assured analgesia in almost every case. Medetomidine resulted in marked bradycardia, lasting as long as the sedation and the ECG revealed a sinus arrhythmia with sinoatrial and atrioventricular blocks grade I and II as a sign of interference with transduction. The bradycardia with xylazine plus l-methadone was less pronounced. A decrease in respiratory rate accompanying sedation had no influence on blood gases and blood acidity in the dogs treated with medetomidine but caused a respiratory acidosis with xylazine plus l-methadone. Body temperature decreased with all treatments for the duration of the period of sedation. Blood glucose concentration increased to a similar extent in all treatment groups, but all other haematological and clinicochemical variables remained unchanged. Treatment with the specific alpha 2 antagonist, atipamezole, reversed the sedation and cardiovascular and pulmonary effects due to medetomidine within minutes.
