“Surprisingly, “minor” surgical procedures were associated with high pain intensities … … procedures that have the reputation of being less painful received inadequate pain relief”

Pathophysiology of chronic postsurgical pain

• Injury to the peripheral nerves

• Central sensitization

• Loss of descending control

• Influence from higher centres

• Genetic predisposition

• Published by NHMRC (Australia) – 1st edition: 1999

– 2nd edition: 2005

– 3rd edition: 2010

• The whole process of acute pain management was reviewed

• “Key messages” with level of evidence according to NHMRC designation

• Published by NHS in 2004

• “A designated consultant anaesthetist should be responsible for acute pain management.”

• “All nursing staff, and all other healthcare professionals involved in postoperative pain management should have an up-to-date, evidence-based and appropriate understanding of postoperative pain management.”

“Nurse-led” Acute Pain Service

• Started in some European countries

• More cost-effective

• Growing interest in the development of pain management as a nursing specialty

• “Pain as the Fifth Vital Sign” has been advocated to have pain assessment for all patients

• Published by ASA in 2004

• Revised in 2012

• “Preoperative evaluation” - formulation of pain plan

• “Multi-modal” techniques for pain management

• Working group consisting of anaesthesiologists and surgeons

• Postoperative pain management should be “procedure-specific” because the type, level and duration of pain may vary depending on the type of surgery.

Thoracic epidural is superior to systemic opioids in relieving pain. It should be continued

for 72h.

Recommendations for acute pain service

• Include all patients after surgery

• Include all types of surgery

• Nurse-led service

• Perioperative service – from preoperative evaluation to postoperative follow-up

• Collaborate with surgeon

• Procedure-specific protocols

Page 25: Perioperative Pain Management - Hospital Authority€¦ · Nurse-led Acute Pain Service •Link nurses –Nurses from the operating theatre (OT) and ward –Collaborating with the

… the acute pain service has to be extended

to cover all patients having surgery.

With more nurses willing to participate in the management of postoperative pain,

anaesthesiologists can step back and assume a supervisory role.

In collaboration with the surgeons, postoperative pain management and

rehabilitation protocols should be established to facilitate recovery after

specific surgical procedures.

Nurse-led Acute Pain Service

• Advanced Practice Nurse (APN) in Pain Management

– Completed Post Registration Certificate Course (PRCC) in Pain Management

– Dedicated pain nurses providing full-time service

– Supervised by the anaesthesiologist

– Total number in the territory < 20

Nurse-led Acute Pain Service

• Link nurses

– Nurses from the operating theatre (OT) and ward

– Collaborating with the pain nurses

– Total about 70 from the OT and 380 from various wards (territory-wide)

– Most of them have not received formal training in pain management

• Perioperative Care Enhancement Programme

– Piloted in QEH in July 2014

– A team of Pain Nurses and OT nurses, under anaesthesiologists’ supervision and endorsed by surgeons

– Pre-operative visit to all elective surgical patients undergoing anaesthesia

– Intra-operative care

– Post-operative visit within 48h after surgery
