[Postoperative pain assessment in head and neck cancer surgery: benefit of patient controlled analgesia (PCA)].
Acute postoperative pain has seldom been assessed in head and neck cancer surgery. The estimation of actual pain is more difficult when communication is impaired by tracheotomy or tracheostomia. The aim of the present prospective study was the assessment of analgesia level during the first 48 postoperative hours after head and neck cancer surgery. The analgesic procedure involved intra-venous morphine injected by means of a PCA pump (Patient controlled analgesia). Thirty patients were thus treated after cancer surgery of the larynx or the oropharynx. The protocol included during 48 hours the assessment of pain, using a visual analogic scale (VAS) every fourth hour, while recording the total injected dose of morphine, the localisation of pains, as well as the occurrence of side-effects. The control of postoperative pain was shown to be satisfactory, with a VAS grade smaller than 3 at time zero and kept below this value during 48 hours. At the end of this period, the mean total dose of morphine injected was 38 mg. No case of respiratory depression was even seen. It can be concluded that PCA seems to be an efficient procedure for controlling postoperative pain in head and neck cancer surgery. This technique proved to be better than delivering analgesia on requirement.
