Pre-Operative

Expand all

In this section, data are available from studies that assessed pre-operative analgesia versus pre-operative placebo, as well as those that examine the concept of pre-emptive – or preventive – analgesia, assessed pre-operative analgesia versus the same analgesia given postoperatively.

A previous systematic review of pre-emptive analgesia for postoperative pain relief in a variety of surgical procedures – such as orthopaedic, dental, gynaecological and abdominal – concluded that there is no benefit of pre-emptive over postoperative administration (Møiniche 2002). More recently, a meta-analysis of studies comparing pre-operative interventions with similar postoperative interventions in various procedures, found that pre-operative epidural analgesia was effective in reducing postoperative pain scores, but that pre-operative NSAIDs, local anaesthetic wound infiltration, NMDA antagonists and opioids did not improve postoperative analgesia (Ong 2005b).

 Despite these findings, it is considered that analgesic medication needs to be initiated in time to ensure an adequate analgesic effect in the immediate postoperative period. This may necessitate administration prior to the postoperative period.

PROSPECT Recommendations

  • Clonidine is not recommended (Grade D), despite limited procedure-specific evidence for analgesic efficacy, because it is associated with an increased risk of hypotension and bradycardia (LoE 4)

Clinical Practice

  • The risk:benefit ratio for clonidine is unclear. Recognised side-effects include hypotension, sedation, dizziness and bradycardia
  • There is no consensus among clinicians on the optimum dose of clonidine that should be used

PROSPECT Recommendations

  • Pre-operative COX-2-selective inhibitors are recommended (Grade B) for colonic resection based on procedure-specific evidence that they have an analgesic effect postoperatively (LoE 2), only for patients who do not receive epidural analgesia (LoE 4)
  • It is recommended that the use of COX-2-selective inhibitors should depend upon assessment of individual patient risks (Grade B): cardiovascular morbidity (transferable evidence, LoE 1), renal function and hepatic function (transferable evidence, LoE 3), or actual or recent gastroduodenal ulcer history (LoE 4). In addition, the potential risk of anastomotic leakage needs to be considered (transferable evidence, LoE 3). Further observations are required regarding the potential risk of N

PROSPECT Recommendations

  • Pre-operative corticosteroids are not recommended for analgesia (Grade A) because of procedure-specific evidence showing no significant benefit in reducing VAS pain scores (LoE 1) and concerns that they could affect anastomotic and wound integrity (LoE 4).

PROSPECT Recommendations

  • Continuous administration of IV lidocaine limited to the pre-/intra-operative period is not recommended (Grade D, LoE 4) because of inconsistent and insufficient procedure-specific evidence (LoE 1)

  • [No data found within the parameters of the systematic review]

PROSPECT Recommendations

  • Pre-operative administration of weak opioids is not recommended (Grade B) based on procedure-specific evidence that it has limited postoperative analgesic benefit compared with postoperative administration (LoE 2)

Clinical Practice

  • Tramadol 300 mg is considered to be a clinically effective dose, and therefore the 100 mg dose used in the study by Wordliczek et al. is probably too low to provide sufficient pain relief

Transferable Evidence from Other Procedures

  • A systematic review of pre-emptive analgesia for postoperative pain relief in a variety of surgical procedures – such as orthopaedic, dental, gynaecological and abdominal – has concluded that there is no benefit of pre-emptive over postoperative administration
  • A meta-analysis of studies comparing pre-operative interventions with similar postoperative interventions in various procedures found that pre-operative NSAIDs and local anaesthetic wound infiltration improved analgesic consumption and time to first rescue analgesic request, but not pain scores. Evidence did not support an improvement in postoperative analgesia following administration of pre-operative NMDA antagonists and opioids

PROSPECT Recommendations

  • Continuous thoracic epidural anaesthesia and analgesia at a level appropriate to the site of incision are recommended for routine use (Grade A), based on superior postoperative analgesic and safety benefits compared with systemic techniques (procedure-specific evidence, LoE 1, also see Intra-operative and Postoperative Epidural Analgesia sections), except in a minority of patients with a contra-indication to epidural administration
  • Pre-operative administration of a single-shot epidural analgesia produces a similar postoperative analgesic efficacy to postoperative administration
  • Where epidural techniques are used, it is recommended that a combination of strong opioid and local anaesthetic is used (Grade A) because of the increased analgesic efficacy of the combination compared with strong opioids alone and to reduce the dose of strong opioid and its associated side-effects (procedure-specific evidence, LoE 1, see Intra-operative and Postoperative Epidural Analgesia sections)
  • Where epidural techniques are used, it is recommended that the epidural catheter is inserted pre-operatively because this is the most practical timing for insertion (Grade D, LoE 4)

Clinical Practice

  • In colonic surgery, the analgesic and recovery benefits of an epidural outweigh the risks of rare major complications and warrant the use of this more labour-intensive treatment
  • Where epidural techniques are used, the most practical timing for insertion of the epidural catheter is pre-operatively
  • 1 mg epidural morphine is considered inadequate to block visceral pain; however, larger doses are likely to cause bladder dysfunction. Therefore, pre-operative epidural administration of local anaesthetic with opioids is preferred to opioids alone

PROSPECT Recommendations

  • Spinal morphine is not recommended (Grade D) because of the risk of side-effects (LoE 4)
  • Spinal clonidine is not recommended (Grade B) because of limited analgesic effect (procedure-specific evidence LoE 2) and the risk of side-effects (LoE 4)

Clinical Practice

  • Spinal morphine may produce some postoperative pain relief but also produces risk of PONV and prolongation of postoperative ileus, and limited duration of analgesic effect

PROSPECT Recommendations

  • Bilateral TAP block is not recommended at the current time (Grade D, LoE 4) because of limited procedure-specific evidence, despite some positive transferable evidence (LoE 1)

Clinical Practice

  • The single-shot TAP block technique may provide effective postoperative analgesia but the duration is limited. Despite this, further study evidence is expected which may support the use of this technique
