Com formular la pregunta

  • P-> Problema: dolor agut
  • I-> Intervenció: AINE VO

 En cuanto a la vía de administración de los AINE, la revisión Cochrane [1] sugiere que
 no hay evidencia para recomendar otra vía que no sea la oral en la lumbalgia aguda.

The objective of this systematic review was to assess the effects of NSAIDs in the treatment of non-specific low back pain and to assess which type of NSAID is most effective [1].

Acute pain management in older adults. National Guideline Clearinghouse (USA). 2006. link. 

 Avoid intramuscular (IM) administration in older adults. 
 Because of muscle wasting and less fatty tissue in older as compared to younger adults, 
 intramuscular absorption of analgesics in older adults is slowed 
 and may result in delayed/prolonged effect of IM injections, 
 altered analgesic serum levels and possible toxicity with repeated injections [2, 3, 4, 5]. 
 Evidence Grade = B
  • Variable pain control following intermittent intramuscular meperidine injections was shown to be due to inadequate, fluctuating and unpredictable blood concentrations [2].
  • The purpose of this study was to identify patient patterns in intravenous patient-controlled analgesia (PCA) and intramuscular (IM) analgesia for patients after surgery [3].
  • Patient-controlled analgesia (PCA) allows patients to self-administer small boluses of narcotic, allowing better dose titration, enhanced responsiveness to variability in narcotic requirements, and reduction in serum narcotic level fluctuation [4].

    • OBJECTIVE: To examine and compare the pharmacokinetics and pharmacodynamics of meperidine when administered intramuscularly at gluteal and deltoid sites in elderly postoperative patients.
    • DESIGN: Prospective, randomized investigation.
    • SETTING: Tertiary care university teaching hospital.
    • PATIENTS: Fourteen patients 60 years of age or older who were undergoing general surgery.
    • INTERVENTION: A single dose of meperidine 0.75 mg/kg given intramuscularly at either a deltoid or gluteal site.
    • MAIN OUTCOME MEASURES: Pharmacokinetic (based on concentration-time curves) and pharmacodynamic (i.e., pain scales, need for additional pain medication) comparisons were made, based on site of meperidine injection.
    • RESULTS: No statistically significant differences were found in the maximum plasma concentration, volume of distribution, or clearance of meperidine by site of injection. Substantial interpatient variability in pharmacokinetic parameters was noted for both sites (range of maximum concentrations: 191-500 ng/mL gluteal, 166-374 ng/mL deltoid). Although pain scores were similar for the two groups, four of the patients in the group given gluteal injection required additional breakthrough pain management within 4 hours of meperidine injection compared with one patient in the group given deltoid injection.
    • CONCLUSIONS: There is no obvious relationship between meperidine pharmacokinetic and pharmacodynamic parameters, regardless of intramuscular injection site. Breakthrough pain is common when patients are given intramuscular injections postoperatively, particularly when the gluteal route is used. When meperidine is used for analgesia in elderly postoperative patients, consideration should be given to more rapid and predictable routes (e.g., intravenous injection) of meperidine administration.

Comparing analgesic efficacy of non-steroidal anti-inflammatory drugs given by different routes in acute and chronic pain: a qualitative systematic review. DARE. 1998. link. 

 In renal colic there was evidence that NSAIDs act quickest when given intravenously. 
 In all other pain conditions there was a lack of evidence of any difference between administration routes. 
 In pain conditions other than renal colic, there is, therefore, 
 a strong argument to give oral NSAIDs when patients can swallow [6].
  • OBJECTIVE: To compare the clinical efficacy of single doses of intramuscular ketorolac and oral ibuprofen in the emergency department (ED) treatment of acute pain.
  • DESIGN: A retrospective analysis of data collected during a prospective survey of pain management efficacy. The design was noninterventional, and therapy was selected by the treating physician independent of the trial.
  • SETTING: Urban teaching hospital adult patient emergency department.
  • PARTICIPANTS: A convenience sample of ED patients in acute pain.
  • INTERVENTIONS: Patients received ibuprofen 800 mg po (n = 95), or ketorolac 60 mg im (n = 30) as a single dose. Therapy was selected by the treating physician and was not influenced by the study.
  • RESULTS: Data collected were a 100-mm visual analog pain scale at patient arrival and discharge, verbal description of pain relief, patient demographics, pain management data, and discharge diagnosis. Baseline pain intensity was higher in patients receiving ketorolac (77 mm median) than in those receiving ibuprofen (65 mm, p = 0.02). Pain relief was similar (p = 0.29) with either treatment when assessed by visual analog scale or patient definition of pain relief. CONCLUSIONS: A single dose of either nonsteroidal antiinflammatory drug produced similar pain relief in the general ED population during clinical treatment of pain. Ketorolac should not necessarily be considered a more effective analgesic than ibuprofen in these commonly used doses.

Conclusions

  • [1]: no és una revisió exactament sobre el què busquem.
  • [2]: estudi descriptiu. Les injeccions intramusculars tenen una absorció erràtica mirant les concentracions del fàrmac en sang.
  • [3]: no és el què busquem.
  • [4]: no és el què busquem.
  • [5]: estudi randomitzat. N=14. Les injeccions intramusculars tenen una absorció erràtica mirant les concentracions del fàrmac en sang.
  • [6]: revisió sistemàtica d'assajos clínics. N=2225. Excepte en el còlic nefrític no hi ha evidència que cap de les rutes sigui millor que la oral.
  • [7]: anàlisi retrospactiu. N=?. El ketorolak IM no ha demostrat ser millor que l'ibuprofè VO.

Aplicació pràctica

 Davant d'un pacient amb dolor agut, millor intentar un tractament via oral, 
 a no ser que sigui un còlic nefrític o que el pacient no pugui deglutir. 
 L'absoció de la via intramuscular és erràtica.
