A thorough understanding of the physiological repercussions of the pneumoperitoneum is essential in order ot properly grasp the safety rules governing anesthesia for laparoscopic surgery. As a general rule systemic vascular resistance increases as the heart flow rate and venous return circulation decrease. Variations in the ventilation/perfusion ratio explain the origin of hypercapnia observed in patients.

Motor axons can form sprouts from their terminal arborizations in response to partial denervation, and when exposed to pharmacological blocking agents like TTX, botulinum toxins alpha-bungarotoxin, or curare. Each of these experimental procedures has cessation of muscle contractile activity as a common feature. We tested the specific role of muscle fiber inactivity in regulating nerve terminal sprouting by chronically treating adult frog (Rana pipiens) cutaneous pectoris muscles with formamide.
