Effects of aging and propofol on the cardiovascular component of the autonomic nervous system.
To determine the combined effects of aging and propofol on autonomic nervous system activity using heart rate variability (HRV) analysis. ⋯ Propofol and aging act in synergy to depress the activity of the cardiovascular component of the autonomic nervous system. However, a compensatory increase in sympathetic outflow was seen in young patients. Such counterbalance was not observed in the older group.

To report the use of ultrasound for cyroablation of purely sensory nerves for long-term relief of pain because the use of ultrasound enhances accuracy while minimizing injury to surrounding structures. ⋯ Neuro-ablative procedures using cryotherapy have been well reported. The use of ultrasound with cryotherapy facilitates direct visualization of the anatomy and aids in avoidance of vital vascular and pleural structures.

A patient developed brisk airway bleeding after being discharged earlier that day following an uneventful partial vocal cord cordectomy. This emergent complication required management by the team of anesthesiologists and otorhinolaryngologists. A plausible explanation for the occurrence of this complication was the presence of aberrant arterial blood supply in the area of the vocal cords where the surgery was performed.
