Using opiate-free aesthesia may cut need for pain-killers

London: Patients undergoing breast cancer surgery need less pain-killing medication post-surgery if they have aesthesia that is free of opioid drugs, new research suggests. While opioid drugs provide an excellent pain-killing (algesia) effect throughout operations, they also have side effects, the researchers said. Post-operative complications, such as respiratory depression, post-operative usea and vomiting, itching, difficulty going to the toilet and bowel obstruction are some examples of side effects.

The findings showed that patients in the non-opiate group require less pain-killers, but receive adequate pain relief.

Patients require less algesic 24 hours after a non-opiate aesthesia than after an opiate aesthesia.

“Non-opiate aesthesia in breast cancer surgery might avoid several opiate-related side effects such as post-operative usea and vomiting. It might also reduce cancer recurrence,” said Sarah Saxe from Jules Bordet Institute in Belgium.

“However, it is too early to recommend non-opiate aesthesia to all breast cancer patients,” Saxe added.

In the study, pain-killer requirements were examined after patients received opiate aesthesia and non-opiate aesthesia.

A randomised controlled trial was conducted, containing two groups each containing 33 breast cancer patients undergoing a mastectomy or lumpectomy.

Both groups received intravenous paracetamol (1000mg/6h) and intravenous diclofec (75 mg/12h).

Patients received a PCA (patient-controlled algesia) pump for breakthrough pain during the first 24 hours post-operatively. (IANS)
