Acute pain following needlescope-VATS (nVATS) sympathectomy for palmar hyperhidrosis

"...recently Sihoe et al. [10] have reported that pre-emptive wound infiltration with a local anaesthetic reduces the postoperative wound pain following needlescope-VATS (nVATS) sympathectomy for palmar hyperhidrosis. The concept of pre-emptive analgesia has gained popularity following
experimental work, demonstrating that early control of pain can alter its subsequent evolution as well as the recognition that nociception produces important physiological responses, even in adequately anaesthetised individuals, and the understanding that for many individuals the minimisation of pain can improve clinical outcomes [11].
The pre-emptive analgesia is based on the intuitive idea that if pain is treated before the injury occurs, the nociceptive system will perceive less pain than if analgesia is given after the injury has already occurred. The preoperative administration of analgesic will modify the afferent nociceptive barrage from the site of injury, thus preventing the development of central sensitisation and hyperalgesia [12].
Thus, we have focussed on this argument in the aim of the present study, which is to determine whether pre-emptive local analgesia (PLA) has an effect to reduce acute postoperative pain following standard-VATS (s-VATS) sympathectomy, in view of n-VATS being considered less painful
than the s-VATS procedure [4,5]."
