Anaesthesia
-
Difficult and/or failed intubation occurs in ~1 in 200 general anaesthetics, more commonly with emergency surgery, obesity, increased morbidity and with neuro or endocrine surgery.
pearl -
Current evidence is too limited to conclude any significant difference between phenylephrine and noradrenaline for managing CS hypotension due to spinal anaesthesia.

Randomized Controlled Trial
The effect of a low-dose naloxone infusion on the incidence of respiratory depression after intrathecal morphine administration for major open hepatobiliary surgery: a randomised controlled trial.
Intrathecal morphine is an analgesic option for major hepatopancreaticobiliary procedures but is associated with a risk of respiratory depression. We hypothesised that a postoperative low-dose naloxone infusion would reduce the incidence of respiratory depression without an increase in pain scores. Patients scheduled for major open hepatopancreaticobiliary surgery and who were receiving 10 μg.kg-1 intrathecal morphine were eligible for inclusion. ⋯ The incidence of respiratory depression was lower in the naloxone group compared with the control group (10/48 vs. 21/47 patients, respectively; p = 0.037, relative risk 0.47 (95%CI 0.25-0.87). Maximum pain scores were greater for patients allocated to the naloxone group compared with control (median 5 (95%CI 4-6) vs. 4 (95%CI 2-4), respectively; p < 0.001). A low-dose naloxone infusion decreases the incidence of respiratory depression following intrathecal morphine administration in patients having major hepatopancreaticobiliary surgery at the expense of a small increase in postoperative pain.

Multicenter Study
10 kHz spinal cord stimulation for the treatment of non-surgical refractory back pain: subanalysis of pooled data from two prospective studies.
Spinal cord stimulation at 10 kHz is a promising therapy for non-surgical refractory back pain; however, published data are currently limited. We present a subanalysis of prospectively collected clinical outcome data for non-surgical refractory back pain patients treated with 10 kHz spinal cord stimulation, from the independent cohorts of two previous studies (SENZA-RCT and SENZA-EU). Clinical outcomes were evaluated at pre-implantation (baseline), 3 months, 6 months and 12 months following 10 kHz spinal cord stimulator implantation. ⋯ At 12 months, the combined cohort had an average decrease in ODI scores of 15.7% points from baseline and opioid use more than halved. In conclusion, 10 kHz spinal cord stimulation reduced pain, disability and opioid consumption in non-surgical refractory back pain subjects. Application of this therapy may improve the care of non-surgical refractory back pain patients and reduce their opioid consumption.
