PROSPECT Recommendations

  • Pre-operative systemic clonidine is not recommended (Grade D) because procedure-specific evidence for analgesic efficacy is limited and because of potential adverse-effects, which may delay early ambulation (LoE 4)

Clinical Practice

  • The risk/benefit ratio for clonidine is unclear. Recognised side-effects include hypotension, sedation, dizziness and bradycardia

PROSPECT Recommendations

  • Pre-operative conventional NSAIDs are not recommended (Grade B) (majority vote of the Working Group; 6:2).

  • There is insufficient evidence that pre-operative administration is of greater analgesic benefit than intra- or postoperative administration (transferable evidence, LoE 1)

Clinical Practice

  • [None cited]

PROSPECT Recommendations

  • Pre-operative strong opioids are not recommended (Grade B) for analgesia because of side-effects during recovery (transferable evidence, LoE 1)

Clinical Practice

PROSPECT Recommendations

  • Pre-operative tramadol is not recommended (Grade B) for analgesia because of side-effects during recovery (transferable evidence, LoE 1)

Clinical Practice

  • Tramadol is a centrally acting analgesic with µ-opioid agonist (M1-metabolite) and aminergic mechanisms of action. For prescription purposes, it is considered a weak opioid or a non-narcotic in most countries
  • Tramadol is useful in the treatment of postoperative pain of moderate intensity (intravenous and oral administration), providing effective analgesia in the in-patient and ambulatory setting
  • The effects of weak opioids on gastrointestinal (transit, secretion) and sphincter function, are of a lesser magnitude than those of strong opioids
  • At recommended doses, tramadol has no clinically relevant effects on cardiovascular or respiratory parameters, thus the risk of respiratory depression is negligible
  • Tramadol is beneficial when conventional NSAIDs are contraindicated
  • The oral solution (drops) of tramadol is useful as rescue medication when paracetamol/conventional NSAIDs/COX-2-selective inhibitor analgesic regimens are used
  • Opioid adverse effects, especially nausea and dizziness, limit the usefulness of tramadol, but many of the effects are less than for strong opioids
  • When ondansetron is used for the treatment/prophylaxis of tramadol-induced nausea and vomiting, a decrease in analgesic efficacy has been reported

Transferable Evidence from Other Procedures

  • Tramadol was more effective than placebo for pain relief in a meta-analysis of post-surgical patients Moore et al 1997
  • The combination of tramadol and paracetamol enhances analgesic efficacy compared with either agent alone McQuay H et al 2003
  • A systematic review found that the combination of dextropropoxyphene 65 mg with paracetamol 650 mg showed similar efficacy to tramadol 100 mg but with a lower incidence of adverse effects Collins et al 2000
  • A systematic review found that the combination of codeine with paracetamol provided additional pain relief compared with paracetamol alone Moore et al 2000
  • Adverse effects associated with tramadol include headache, nausea, vomiting, dizziness, somnolence. A meta-analysis of individual patient data from randomised controlled trials found a dose-response of adverse effects with tramadol; postsurgical patients had fewer side-effects than dental patients Moore et al 1997
  • A systematic review found that the combination of codeine with paracetamol was associated with an increase in drowsiness and dizziness compared with paracetamol alone Moore et al 2000
  • A systematic review found an increased incidence of central nervous system adverse effects with paracetamol plus dextropropoxyphene compared with placebo Collins et al 2000

PROSPECT Recommendations

  • Long-acting LA wound infiltration is recommended (Grade A) for reducing wound pain (procedure-specific evidence, LoE 1), but not for reducing shoulder pain (procedure-specific evidence, LoE 1)
  • There is evidence that pre-operative administration is of no greater analgesic benefit than intra- or postoperative administration (procedure-specific evidence, LoE 1)

Clinical Practice

  • Long-acting local anaesthetics are preferred to short-acting local anaesthetics for analgesia by local injection
  • Intra-operative wound infiltration is a well-established method of analgesia with a favourable safety profile
  • The dose of LA must be monitored to ensure that maximum dose limits are not exceeded, especially if both infiltration and IP LA techniques are used

Transferable Evidence from Other Procedures

  • A qualitative and quantitative systematic review of intraperitoneal, port-site infiltration and mesosalpinx block confirmed that intraperitoneal infiltration showed statistically significant but clinically questionable effect on postoperative pain; mesosalpinx local anaesthetic block, but not port-site infiltration, had some impact on postoperative pain after laparoscopy Møiniche et al 2000
