Barreveld et al. show that LA administered either IV or via block; before, during or after surgery, significantly reduces postoperative pain and opioid consumption.
Specifically in:
• Total knee arthroplasty (femoral, sciatic and lumbar plexus b., single-shot or continuous)
• Total hip arthroplasty (continuous lumbar plexus; intra-articular LA)
• Knee arthroscopy (single-shot lumbar plexus; IA LA; single-shot femoral nerve ± sciatic).
• Arthroscopic shoulder surgery - interscalene b., single-shot or continuous. IA is not beneficial.
• Hand & forearm surgery - axillary b. offers analgesic benefits only on day of surgery.
• TAP block is beneficial for laparoscopic, open appendectomy, abdominal surgery, cesarean section, and TAH.

Intravenous lidocaine is efficacious and may be a suitable alternative to regional anesthesia when contraindicated or not performed.

Nerve blocks in general have a beneficial analgesic effect, regardless of whether pre- or post-incision, and are superior to intra-articular LA.

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:
1. Intubating patients without muscle relaxants is less safe and sub-optimal.
2. Even if you know muscle relaxant pharmacokinetics, it is sufficiently unpredictable that neuromuscular monitoring and reversal is still necessary.
3. Post-operative residual curarization (PORC) is clinically significant with real consequences.
4. Postoperative residual curarization (PORC) is common.
5. Postoperative residual curarisation (PORC) (TOFR < 0.9) can only be diagnosed with a quantitative neuromuscular monitor. Clinical tests are insufficient and poorly sensitive.

Excellent anaesthetists were identified by anaesthesia nurses as being:
1. Organised & focused: structured, responsible, and focused approach to work tasks.
2. Good communicators: clear and informative, briefing of team about the plan before induction.
3. Respectful of complexity: humble to the complexity of anaesthesia, admitting own fallibility.
4. Patient-centred: personal contact with the patient before induction.
5. Good situational awareness: fluent in practical work without losing overview.
6. 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.
