Detailed Description
Postoperative pain can contribute to reduce the patient well-being and, if it is pronounced, delay rehabilitation and increase the total cost for nursing and treatment.
As quite extensive surgical procedures presently are being undertaken on an ambulatory basis the need for adequate post-operative pain prophylaxis is stressed. Pain and nausea/vomiting are the most frequent causes of delayed discharge or unanticipated admission to hospital stay after ambulatory surgery (1). As opioids for postoperative pain relief have a lot of unwanted side-effects (e.g. nausea, vomiting, sleepiness, obstipation, disturbed physiological sleep [2]), it has been shown beneficial, both in terms of cost-effectiveness and patient satisfaction, to reduce the need of opioids in post-operative setting by other means (i.e. non-opioid) methods of pain-relief. The concept of multimodal, non-opioid pain prophylaxis and treatment is being advocated as optimal after ambulatory surgery. The most important modes of non-opioid pain prophylaxis, at present, is paracetamol, non-steroidal anti-inflammatory drugs (NSAIDs) and local anaesthesia. The best result is achieved when these different modes are used together in a prophylactic manner; the need of rescue opioid analgesics may be reduced by 20-50% and in many cases diminish (3). It has been shown in many studies that the NSAID is an important component in routine post-operative pain prophylaxis, e.g. NSAID in combination with paracetamol provides better analgesic effect than paracetamol alone, and may be equianalgesic to a small-medium dose of opioid (2).
There are four problems with NSAIDs when used for routine pain prophylaxis in ambulatory surgery/anaesthesia: increased bleeding tendency, gastrointestinal ulceration, renal failure and anaphylactic reactions (2-4).
There are definite potential benefits with etoricoxib in ambulatory setting (5-7): Due to cox-II selectivity there is no concern of increased bleeding tendency; thus the drug can be given pre-operatively. It is a potent, oral coxib; thus cheaper and more simple than IV NSAIDs. It has a long duration of effect; thus the need of patient attention is reduced because the first dose lasts for 24 h and a single daily dose will be optimal further on.
It has a lower potential of gastrointestinal ulceration, thus may be used in some patients where conventional NSAIDs may be contraindicated.
It has so far not been shown to have harmful cardiovascular effects in prospective studies of continuous use for at least 12 months in patients with increased risk of cardiovascular complications (ref 8: Edge study).
Study rationale: Etoricoxib has so far been compared with traditional oral NSAIDs and oral coxibs for postoperative pain prophylaxis. However, in many clinical situations the use of pre-operative conventional NSAIDs is not recommended due to the risk of preoperative bleeding. These patients are usually given IV ketorolac during the last part of the procedure as the most efficient alternative for post-operative pain prophylaxis.
It will be of great interest to compare this practice with the use of oral etoricoxib given pre-operatively. If the analgesic quality of an adequate dose etoricoxib is comparable to a ketorolac regimen, the etoricoxib approach will have a lot of potential benefits: simple, cheap, earlier start of analgesia, more longlasting analgesia and less risk of postoperative bleeding and gastrointestinal ulcer. If successful, a single pre-operative dose of etoricoxib may be a routine measure in a majority of all ambulatory surgery patients.
Hypotheses: A single dose pre-operative of oral etoricoxib 120 mg will have equal post-operative analgesic efficacy as an optimal regimen of IV ketorolac 30 mg + 30 mg during the first 18 h( +/- 1 h) after gynaecologic laparoscopic surgical procedure, where the need for post-operative opioid is expected.
