Analgesia Post Craniotomy Surgery Dundee

 

Traditionally, craniotomy was thought to be less painful than other surgical procedures. Recent evidence has challenged this, with one study finding 55% of subjects reporting moderate to severe pain on Day 1 post-op. Pain delays recovery, prolongs hospital stay and increases rates of complications.

We aim to collect data on current practices in the perioperative management of pain in adult patients following elective supra-tentorial craniotomy under general anaesthesia (i.e. not awake craniotomy) .

Thank you for taking the time to complete this survey. If you have any other comments you would like to make or share please feel free to enter in the box below.

 

Although I find the use of NSAIDs acceptable, surgical tradition means we do not use  them perioperatively following craniotomies.

 

Although I’m not involved in theatre with these cases on a regular basis I do run the Acute Pain Team here. I’m not sure what the questions in the survey would have asked but our regime for these craniotomies is 1) iv paracetamol qds x 24h, then oral 2)NSAID  at 6 h if all is Ok and no other contraindication (omit any functional neurosurgical case). Continue regular x 48h and then review 3)oramorph 5 mg qds + 3hourly prn 5-10 mg 4) big push to encourage scalp block at end of op

 

Departmental guidelines are just to avoid prescribing codeine and to stick to oral morphine at a dose of 5 or 10 mg qds along with paracetamol. There are no guideline with regards to prescribing non steroidals although most patients do not seem to need them      Filled in on behalf of my colleagues. We are a children’s hospital so don’t anaesthetise  enough patients over the age of 16 to qualify!

 

I dont understand why I keep on finding codeine prescribed for perioperative analgesia  by surgical teams many thanks, best wishes

I use a lot of the analgesics listed but not routinely for most cases so my answers to your questions are limited to Paracetamol & Morphine. Each patient is different and I’m  happy using to use clonidine, fentanyl,scalp blocks, IV lidocaine, ketamine depending on the individual patient.

 

If unable to swallow, codeine, i.m. or p.r., still works. It is not part of the culture in Cardiff to use NSAIDS because )I think) they are regarded as unnecessary, rather than      hazardous. Adding NSAIDS at/after 4-hours-postop would be acceptable to me.

many thanks, there are craniotomies and craniotomies of course ……               Most patients will receive dexamethasone(i.e. a steroidal anti-inflammatory drug) during  surgery, and many will have this started pre-op and continued post-op.

 

my main work seems to be complex backs so whilst I DO CRANIOTOMIES they are not  monthly but come like buses.

One aspect of postoperative craniotomy pain is related to the use of head bandages.       These are frequently uncomofrtable, hot and aggravating.

 

Rct’s and dosing studies on paracoxib show it is safe for use in craniotomy patients however there is no improvement in 24hr opioid use. I do use scalp blocks but not for all my patients. From metaanalysis, there is only significant improvement in the first 4-6hrs  post op when compared to short acting opioids. Gabapentin is useful in some patient groups. Since using oxynorm intraop and in recovery 24hr use of morphine pca dropped to less than 15mg hence I no longer use this.

 

Recent word from Pain team is that our craniotomy patients are rarely in pain after craniotomy and rarely need more than simple oral analgesics or med strength opioids        on ward.

 

Surprised by your finding re incidence of post op pain. Firm believer in pre-emptive analgesia – iv paracetamol, oxycodone (10mg+) in anaesth room, LA infiltratration w Bupiv 0.5% pre-incision – not at end of surgery. Rescue analgesia in recovery –        oxycodone. Don’t use NSAIDS for “political” reasons. If pt dev post op haematoma, surgeons will immediately blame NSAIDS!!

The survey didn’t differentiate between regular and PRN analgesia. I routinely prescribe regular paracetamol/NSAIDs. Opioids are PRN.Oxycodone only if oramorph contra-   indicated. Just in case my answers are confusing! Apologies.

Use IM dyhydrocodeine when nmb post op too

 

We are unable to give intravenous opiates on the ward and oxycodone can only be            given after discussion with Acute Pain Service

 

We completely an audit in our unit a few years ago that showed supretentorial craniotomy was managed successfully with PRN s/c morphine rather than PCA which was not used regularly in the first 24hrs unlike posterior fossa craniotomy. We have now  moved to regular oromorph which is dispensable by one nurse instead of two a big advantage on a busy ward.      we have no IV preparation of NSAID other than parecoxib on our hospital formulary       Why this obsession with adult patients? Children are an important patient group and  those >8 yrs are accurate reporters of pain.

 

You did not give the option of im codeine in the dysphagic patient question!
