Randomized Controlled Trial Clinical Trial[Analgesic effect of 2 different doses of intra-articular morphine after ambulatory knee arthroscopy. A randomized, prospective, double-blind study].
The effect of intra-articular morphine following knee arthroscopy has been verified in several studies, but the optimal dose has not been established. An earlier study by the authors showed significant effect of one mg morphine versus placebo. In this study, fifty patients were randomized to receive either two or four mg of intra-articular morphine following day-case knee arthroscopy in infiltration analgesia. ⋯ The results showed no significant difference in VAS score between the two dose regimes at any time. Onset of pain after cessation of the local analgesia was not influenced by the morphine dose. On this basis it is recommended to limit the dose of intraarticular morphine, as local adverse reactions to morphine cannot be ruled out.

Randomized Controlled Trial Clinical Trial[Analgesic effect of low-dose intra-articular morphine after ambulatory knee arthroscopy].
The purpose of this study was to demonstrate the effect of intra-articular morphine following knee arthroscopy performed in infiltration analgesia. Fifty-two healthy patients were randomized to receive either morphine 1 mg or placebo. The pain was assessed two, five, eight and 24 hours after the procedure by 1) a VAS scale and 2) the amount of acetaminophen consumed. ⋯ Stratifying data in therapeutic vs. diagnostic arthroscopy suggests an additional effect of morphine in patients undergoing therapy (0.05 < p < 0.10), an aspect which supports the hypothesis of peripherally administered morphine acting as a potential suppressor of the substance P mediated cytokine cascade. Intraarticular morphine 1 mg after knee arthroscopy offers efficient analgesia lasting more than 24 hours. The method is devoid of side effects and deserves wider recognition.

[Patient satisfaction--a study of patients' assessment of the treatment at a department of orthopedic surgery].
A study among day-case and inpatients on an orthopaedic ward has been carried out to assess patient satisfaction. A single-page questionnaire were mailed to 445 patients, 388 (87.2%) returned the questionnaire. Three hundred and fifty five (79.8%) answers were usable. ⋯ The group of patients who underwent arthroscopic surgery were identified as being the most dissatisfied. There were among all patients a large group who were dissatisfied with the amount of perioperative information and especially the amount of postoperative out-patient control. We recommend a higher degree of written information including information about risk of complications and failures.

Randomized Controlled Trial Clinical Trial[Preoperative or postoperative local anesthesia. Effect on postoperative pain treatment].
A randomized, double-blind trial was conducted to compare the efficacy of preincisional and postincisional wound infiltration with 1% lidocaine (40 ml) on postoperative pain. Thirty-seven patients scheduled for elective inguinal herniotomy participated. ⋯ The preincisional lidocaine infiltration group also had fewer patients requiring supplemental analgesics (58%) than the postincisional group (94%) (p < 0.05). We conclude that preincisional infiltration of the surgical wound with lidocaine is a more effective method for postoperative analgesia than postincisional infiltration.
