Rectus sheath and mesosalpinx block for laparoscopic sterilization.

Thirty patients scheduled to undergo laparoscopic sterilisation were allocated at random to receive either a standardised general anaesthetic and rectus sheath block (group A), or standardised general anaesthetic combined with both rectus sheath and mesosalpinx blocks (group B). Group B patients had significantly less postoperative pain, as assessed by linear analogue scores (p less than 0.025), and analgesic requirement (p less than 0.05). By the 8th postoperative hour all 15 group B patients had been discharged from hospital, whilst only seven of 15 patients in group A were considered suitable for discharge at this time, (p less than 0.05).
