New drug to ease C-Section trauma

James Cook University (JCU) researchers may have found a way to reduce trauma and prevent infections after Caesarean births.

Caesarean delivery rates are increasing worldwide and around a third of all mothers in Australia, USA and UK give birth surgically each year, but a C-section is not without risks.

Fourth year medical student Lisa Davenport joined Dr Hayley Letson and Professor Geoffrey Dobson from the Heart, Trauma and Sepsis Research Laboratory at JCU to research ways to reduce the stress response to the trauma of surgery.

Caesarean sections involve one or more incisions in a patient’s abdomen, known as a laparotomy, which Dr Letson described as a major injury.

“It can activate the brain’s stress response from the multiple ‘damage’ signals sent out from the original incision,” she said.

The JCU research showed that a laparotomy causes inflammation and an early activation of the immune system, which can then spiral out of control.

Ms Davenport discovered that adverse responses were reduced when the subject was infused with a small amount of a drip containing Adenosine, Lidocaine and Magnesium (ALM).

Dr Letson said the ALM therapy appears to be linked to improved brain control over whole body function at times of surgical stress. “It suppresses signals that activate immune cells and promote inflammation,” she said.

The work has applications to other major surgery and especially to rural and remote medicine.

Professor Dobson said new frontline drugs are urgently required to make major surgery safer for the patient and more predictable for the surgeon, with the potential to reduce complications and massively reduce health care costs, and possibly reduce waiting times for elective surgery.

“The global surgical statistics are staggering. Of the 234 million major surgeries performed every year, every hour there are around 1000 deaths and 4000 major complications, and 50% may be preventable,” he said.

The research team is also pursuing funding opportunities to investigate the use of ALM fluid as a potential treatment for post-partum haemorrhage. Of the 500,000 maternal deaths each year worldwide, approximately 25% are due to haemorrhage.
