Monitoring neuromuscular blockade with TOF at the eye muscles (orbicularis oculi) results in a 5 times greater risk (adjusted odds ratio) of postoperative residual curarization (PORC) than monitoring at the hand (adductor pollicis) when PORC is defined by TOFR < 90% using acceleromyography.
PORC was nonetheless common in both groups, occurring in 52% and 22% respectively.
Fink & Hollman describe and refute several commonly-held myths regarding neuromuscular pharmacology. Their evidence-supported arguments are:
- Intubating patients without muscle relaxants is less safe and sub-optimal.
- Even if you know muscle relaxant pharmacokinetics, it is sufficiently unpredictable that neuromuscular monitoring and reversal is still necessary.
- Post-operative residual curarization (PORC) is clinically significant with real consequences.
- Postoperative residual curarization (PORC) is common.
- Postoperative residual curarisation (PORC) (TOFR < 0.9) can only be diagnosed with a quantitative neuromuscular monitor. Clinical tests are insufficient and poorly sensitive.
Use of the LMA ProSeal when compared with intubation for gynae-laparoscopy does not decrease post-operative pain or PONV.
Perioperative lidocaine (1.5 mg/kg bolus then 1.5 mg/kg/h until 1 h after skin closure) reduces the incidence of persistent post-surgical pain after breast cancer surgery at 3 months.
Perioperative lidocaine reduces the incidence of persistent post-surgical pain after breast cancer surgery.
Excellent anaesthetists were identified by anaesthesia nurses as being:
- Organised & focused: structured, responsible, and focused approach to work tasks.
- Good communicators: clear and informative, briefing of team about the plan before induction.
- Respectful of complexity: humble to the complexity of anaesthesia, admitting own fallibility.
- Patient-centred: personal contact with the patient before induction.
- Good situational awareness: fluent in practical work without losing overview.
- Calm and clear in critical situations, being able to change to a strong leading style.
Non-technical skills are of equal importance to technical anaesthesia skills, but are more challenging to define, measure and acquire.
Meta-analysis suggests regional scalp block may reduce post-operative pain after craniotomy, although relies on small, low-quality studies.
30mg intraperitoneal nebulized ropivacaine significantly reduces pain after laparoscopic cholecystectomy, reducing opioid use and speeding ambulation.
Implementation of a Surgical Safety Checklist had a positive, though small, impact on the theatre safety culture in a Norwegian university hospital.
