Randomized Controlled TrialTransversus abdominis plane block vs. wound infiltration in Caesarean section: a randomised controlled trial.
Transversus abdominus plane block after caesarean section does not reduce morphine consumption when compared to wound infiltration with equivalent local anaesthesia.

Clinical TrialPre-operative baroreflex sensitivity and efferent cardiac parasympathetic activity are correlated with post-operative pain.
A maladaptation of the autonomic nervous system may been seen in patients with chronic pain that includes persistent changes in the autonomic tone, increased heart rate, and reduced heart rate variability and baroreflex sensitivity. Baroreflex sensitivity and acute pain intensity have been reported to be inversely correlated. However, it is unknown whether the same correlation applies with regard to post-operative pain. In the present study, autonomic function was measured in patients scheduled for minor hand surgery and correlated with early and persistent pain after the procedure. Thus, the cause (autonomic imbalance) was present before the effect (post-operative pain). Our primary hypothesis was that a lower level of pre-operative baroreflex sensitivity is correlated with increased early post-operative pain. ⋯ The findings suggest that a low pre-operative level of baroreflex sensitivity is associated with higher post-operative pain intensity. To our knowledge, this is the first study to show the correlation between baroreflex sensitivity and post-operative pain.

Review Meta AnalysisIntravenous ketamine during spinal and general anaesthesia for caesarean section: systematic review and meta-analysis.
Intravenous ketamine has been used during general and regional anaesthesia for caesarean section. No systematic review and meta-analysis on the desired effects and adverse effects of ketamine administration during caesarean section have yet been performed. ⋯ We conclude that ketamine enhances post-operative analgesia after caesarean section under spinal anaesthesia. There is a paucity of data for several maternal adverse effects as well as for neonatal well-being. Further studies are needed for general anaesthesia.

Randomized Controlled TrialOptimising abdominal space with deep neuromuscular blockade in gynaecologic laparoscopy - a randomised, blinded crossover study.
Insufflation of the abdomen during laparoscopy improves surgical space, but may cause post-operative shoulder pain. The incidence of shoulder pain is reduced using a lower insufflation pressure, but this may, however, compromise the surgical space. We aimed at investigating whether deep neuromuscular blockade (NMB) would enlarge surgical space, measured as the distance from the sacral promontory to the trocar in patients undergoing gynaecologic laparoscopy. ⋯ Deep NMB enlarged surgical space measured as the distance from the sacral promontory to the trocar. The enlargement, however, was minor and the clinical significance is unknown. Moreover, deep NMB improved surgical conditions when suturing the abdominal fascia.

Review Meta AnalysisPre-operative fibrinogen supplementation in cardiac surgery patients: an evaluation of different trigger values.
Pre-operative fibrinogen levels are negatively associated with postoperative bleeding in cardiac surgery patients. The guidelines of the European Society of Anaesthesiology consider the possibility of a prophylactic pre-operative supplementation in patients with fibrinogen levels<`3.8 g/l. The present study is a reanalysis of published data aimed to define the diagnostic accuracy of different values of pre-operative fibrinogen levels in predicting severe post-operative bleeding. ⋯ Correction of pre-operative fibrinogen levels below 3.8 g/l would lead to an excessive rate of inappropriate interventions. Values below 2.5 g/l could be considered.
