A systematic search of the literature between January 2004 and June 2006 identified additional studies of interventions in abdominal hysterectomy, as listed in this folder, together with brief summaries of the study outcomes and a comment from the PROSPECT Working Group regarding the impact of the recent evidence on the recommendations. Additional details of the studies will be included in the main review text at the next full update of the evidence and recommendations.
  • Four out of four studies found that conventional NSAID was superior to placebo or no treatment. In two studies pre-operative conventional NSAID significantly reduced postoperative VAS pain scores at 2 h (at rest and on coughing; Akarsu 2004) and 2, 4, 6 and 12 h (Karaman 2006), compared with placebo. In one study, pre- and intra-operative conventional NSAID significantly reduced postoperative VAS pain scores at 6 h compared with control (no treatment) (Yan 2004). In one study postoperative conventional NSAID significantly increased pain intensity difference (VAS) scores compared with placebo (at 30 min–24 h) and compared with morphine (at 30 min and 1–12 h) groups (Bikhazi 2004)
  • In one study, time to first request for rescue analgesia was significantly longer, and total analgesic consumed was less, following pre-operative conventional NSAID administration, compared with placebo (Akarsu 2004); in another study, PCA morphine consumption was significantly reduced in the group receiving pre-operative conventional NSAID at 2, 4, 6, 12 and 24 h compared with the saline control group (Karaman 2006)
  • In one study there was a significantly higher incidence of nausea and vomiting in the placebo group compared with the pre-operative conventional NSAID group (Akarsu 2004). In two studies there were no significant differences between the incidence of adverse events in the conventional NSAID and placebo groups (Bikhazi 2004; Karaman 2006)

  • Three studies out of three showed COX-2-selective inhibitor superior to control for reducing pain scores:
    • In one study, the pre-operative COX-2-selective inhibitor significantly reduced postoperative VAS pain scores at 1, 2, 4, 6, 8 and 12 h compared with placebo (Karamanlioglu 2004)
    • In one study peri-operative COX-2-selective inhibitor, alone and in combination with gabapentin, significantly reduced postoperative VAS pain scores at rest at 20, 24, 28, 32, 44, 48, 52 and 56 h compared with placebo; VAS pain scores at sitting were significantly reduced in the COX-2-selective inhibitor plus gabapentin group at 20h, and following the COX-2-selective inhibitor both alone and in combination with gabapentin at 24, 28, 32, 44, 48, 52, and 56 h compared with placebo; VAS pain scores at peak expiration were significantly reduced following administration of the COX-2-selective inhibitor alone and in combination with gabapentin at 20, 24, 28, 32, 44, 48, 52, and 56 h compared with placebo; VAS pain scores during coughing were significantly reduced in the COX-2-selective inhibitor plus gabapentin group at 20, 24, 28, 32 h, and following administration of the COX-2-selective inhibitor both alone and in combination with gabapentin at 44, 48, 52 and 56 h, compared with placebo (Gilron 2005)

    • Cumulative morphine consumption was significantly less in the COX-2-selective inhibitor plus gabapentin group compared with placebo at 2, 3, 4, 8, 20, 24, 28 and 32 h postoperatively, and interval morphine consumption was significantly less in the COX-2-selective inhibitor group at 4–8, 8–20, 20–32, 32–44 and 44–56 h and in the COX-2-selective inhibitor plus gabapentin group at all time points recorded after surgery, compared with placebo (Gilron 2005)
    • PCA morphine requirement was significantly less following administration of the COX-2-selective inhibitor, alone and in combination with gabapentin at 1, 8, 12, 16, 24, and 30 h postoperatively, and at 20 h following the COX-2-selective inhibitor plus gabapentin, compared with placebo (Turan 2006)
  • Three out of three studies showed that COX-2-selective inhibitors are not superior to placebo for reducing the incidence of adverse effects
    • In two studies there was no significant difference in the incidence of adverse events between the COX-2-selective inhibitor group and control (Gilron 2005; Karamanlioglu 2004)
    • In one study there was no significant difference between COX-2 inhibitor alone or gabapentin alone compared with placebo, but there was a significantly lower incidence of nausea in the combination of COX-2-selective inhibitor and gabapentin group compared with the placebo group (Turan 2006)

No change to recommendations

  • One study showed that pre-operative oral clonidine did not significantly reduce pain scores both at rest and during movement compared with placebo at all time points assessed (Oofuvong 2005); one study showed that pre- and postoperative oral clonidine significantly reduced pain scores compared with placebo at all time points assessed (Hidalgo 2005

Morphine consumption was significantly lower in the postoperative IV droperidol group at all time points assessed, when compared with control (no droperidol) (Lo 2005)

Not recommended for pain relief due to limited procedure-specific evidence (although droperidol has proven effects on nausea and vomiting)

  • One study showed that pre-operative antihistamine, combined with either a 1.2:1 or a 4.8:1 ratio of antihistamine-morphine mixture for postoperative PCA, did not significantly reduce VAS pain scores at rest or supplemental analgesic requirements at any time point assessed (0–24 h) compared with saline control (Lin 2005)
  • One study showed that neither pre-operative antihistamine alone nor postoperative antihistamine alone significantly reduced VAS pain scores at rest or during movement compared with saline control (Chia 2004)
  • One study showed that patients in the pre-operative antihistamine alone group consumed significantly less morphine at 3, 6, 12, and 24 h postoperatively compared with patients in the postoperative antihistamine alone and saline control groups (Chia 2004)

Not recommended due to limited evidence of analgesic efficacy

  • One study showed that pre- and intra-operative beta-blockers had no effect on VAS pain scores at rest and during movement at all time points assessed compared with saline control (Chia 2004)
  • Patients receiving beta-blockers consumed significantly less PCA morphine at all time points assessed, and the mean total morphine consumption was significantly less, compared with saline control (Chia 2004)

Not recommended because of limited evidence of analgesic efficacy
