A comparative study between bupivacaine (S75-R25) and ropivacaine in spinal anesthesia for labor analgesia.

Background And Objectives: Spinal anesthesia is used for relief of pain during labor and it is associated with low indices of complications. Studies with levorotatory enantiomers of local anesthetics demonstrate higher safety due to the lower cardiotoxicity. The objective of this study was to evaluate the latency and duration of analgesia and maternal and fetal repercussions with bupivacaine (S75-R25) and ropivacaine in spinal anesthesia for labor analgesia.

[Anesthesia in a patient with congenital insensitivity to pain and anhidrosis].

Background And Objectives: Congenital insensitivity to pain and Anhidrosis (CIPA) or hereditary sensory and autonomic neuropathy type IV (HSAN IV) is a rare autosomal recessive neuropathy of the group of hereditary sensory and autonomic neuropathies (HSAN) characterized by insensitivity to pain, anhidrosis, and mental retardation. Since it is a rare condition, reports on the anesthetic conduct in patients with CIPA are not easily found in the literature. The objective of this report was to present the anesthetic conduct in a patient with CIPA undergoing left ankle arthrodesis with placement of an implant, and to discuss the characteristics of this disorder that concern anesthesiologists the most.
