Randomized Controlled Trial Comparative Study Clinical Trial
A comparison between bupivacaine instillation versus ilioinguinal/iliohypogastric nerve block for postoperative analgesia following inguinal herniorrhaphy in children.
This study compared the postoperative pain relief provided by simple instillation of bupivacaine into a hernia wound with that provided by ilioinguinal/iliohypogastric (IG/IH) nerve block. Sixty children undergoing inguinal hernia repair under general anesthesia were randomized to receive 0.25 ml/kg of 0.25% bupivacaine for either IG/IH nerve block or up to 0.5 ml/kg of the same solution for instillation nerve blocks. In the postanesthesia care unit (PACU), a trained blinded observer evaluated the patient's level of postoperative pain using a standardized 10-point objective pain scale. ⋯ The two groups were not significantly different in age, duration of surgery, or anesthesia. There was no significant difference between patients who received the two treatment modalities in their pain scores, analgesic requirements in the PACU, recovery times, and discharge times. These results demonstrate that the simple instillation of local anesthetics into a wound provides postoperative pain relief following hernia repair, which is as effective as that provided by intraoperative IG/IH nerve block.

Randomized Controlled Trial Clinical Trial
[Nalbuphine and piritramid in the postoperative phase in young children. 1. General condition].
The influence of piritramide and nalbuphine versus placebo on the postoperative comfort of 54 children of ASA-group I and II in the age between 1 and 4 years was tested in a randomized double blind trial using the comfort/discomfort scale according to Büttner et al. METHODS. Operations, premedication and anesthesia were standardized. ⋯ The use of supplementary analgesics showed a significant effect in the treatment factor and in the within-subject factor: during the 1-h observation period the placebo group received midazolam significantly more often (64.7%) than the piritramide group (5.9%) or the nalbuphine group (35%). During the following 7 h 29.4% of the children of the placebo group required supplementary analgesics (piritramide: 23.5%; nalbuphine: 20%). Subsequently up to the 24th postoperative hour there was no need for any analgesic in the placebo group, whereas 11.8% of the piritramide group and 15% of the nalbuphine group required analgesics.(ABSTRACT TRUNCATED AT 400 WORDS)

Randomized Controlled Trial Comparative Study Clinical Trial[Postoperative pain therapy with 1-methadone and metamizole. A randomized study within the scope of intravenous on-demand analgesia].
Methadone, a potent long-acting opioid analgesic, is only seldom prescribed for postoperative pain relief in Germany. It was the aim of the present investigation to evaluate its efficacy and to establish an adequate dose range using intravenous patient-controlled analgesia (PCA), as well as to determine possible drug interactions with the antipyretic analgesic metamizol (dipyrone). 120 patients recovering from elective major abdominal, gynaecological or orthopaedic surgery under standardized balanced anaesthesia were randomly allocated to three groups to self-administer intravenous 1-methadone. Demand doses were 0.573 mg (group LD), 1.145 mg (group HD) or 0.573 mg to which 50 mg metamizol (dipyrone) were added (group LM). ⋯ Cardiovascular and respiratory status during the observation period was always normal. 88-93% of patients preferred PCA in comparison with earlier experienced conventional postoperative pain treatment. It is concluded that patients are able to control adequate drug consumption, i.e. to avoid overdosage, by adjusting demand frequency if variable demand dosages are offered. Thus 13-19 mg 1-methadone per day can be recommended as reasonable dose range for pain relief during the early postoperative period.(ABSTRACT TRUNCATED AT 250 WORDS)
