anesthetic management in microvascular surgery

Regional anesthesia has been used to help create local sympathectomy and improve blood flow in plastic surgery procedures involving tissue grafts and flaps. However, anesthetic techniques that reduce systemic vascular resistance must be used with caution in patients with aortic stenosis (AS). Combined neuraxial and general anesthesia with careful titration of the local anesthetic dose can be a safe approach for patients with AS undergoing microvascular procedures. We present the anesthetic management of the first North American penile transplant, on an obese patient with moderate AS...

As the incidence of diabetes mellitus (DM) continues to increase worldwide, more diabetic patients will be presented for surgery and anesthesia. This increase of DM is a consequence of the rise in new patients of type 2 DM, and is likely attributable to rapid economic development, improved living standards, aging population, obesity, and lack of exercise. The primary goal of management in DM is to delay, or prevent the macro- and microvascular complications by achieving good glycemic control. More understanding of the pathophysiology of DM has contributed to the advance of new pharmacological approaches...

Dialysis-dependent chronic kidney disease (CKD) is an expanding problem for healthcare systems worldwide. The prevalence of end-stage renal disease (ESRD) has increased by 20% since 2000 and stands at 1699 per million people in the USA. ESRD is associated with an increased risk of cardiovascular comorbidity, increased severity of cardiovascular disease, and an adjusted all-cause mortality rate that is 6.4-7.8-fold higher than the general population. These patients may present electively or emergently for surgery related to, or remote from, the CKD...

The combination of advances in microsurgery and the improvement of anesthetic management with increased understanding of the physiology of preoperative and postoperative care has significantly raised the upper age limit for free-flap transfer in elderly patients. Despite pessimistic opinions regarding elderly patients who have poor recovery potential and decreased physiological reserves, the unique feature of free-tissue transfer is that it allows the transfer of well-vascularized tissue to defects in a single-stage procedure, and leads to improved quality of life...

Because short-latency evoked potentials are relatively resistant to anesthetic agents, they can be used to monitor neural pathways during surgical procedures. The use of median nerve somatosensory evoked potentials to localize the central sulcus is an established aid of indisputable value in neurosurgical procedures involving cortical incisions for resection of certain epileptic foci, vascular malformations, or neoplasms near the central area of the brain. Likewise, recording of intraoperative nerve action potentials is currently regarded as indispensable in management of the neuroma-incontinuity after peripheral nerve trauma, as this evoked potential monitoring technique provides the only reliable method of distinguishing between axonotmetic and neurotmetic lesions...
