Case ReportsSpinal anesthesia using a continuous spinal catheter for cesarean section in a parturient with prior surgical correction of scoliosis.
This case report demonstrates the successful anesthetic management of cesarean section for a 29-year-old primiparous parturient with a past history of a scoliosis operation at 13 years of age. An Isola hook and screw-rod system had been implanted as posterior spinal instrumentation at the level of T3-L3. We titrated hyperbaric bupivacaine 7 mg combined with fentanyl 15 microg through a continuous spinal catheter, placed with a catheter-over-needle technique in order to avoid unintentional wide spread of anesthetic agents. ⋯ Her surgery was carried out without any problems. Headache, as a dural tap-related complication, was not observed. Spinal anesthesia with the titration of anesthetic agents for cesarean section is considered to be one of the choices for a parturient who has had spinal instrumentation.

Case ReportsAberrant halt of syringe pump motion: an improved system to prevent false setting of the syringe.
A syringe pump is used to inject precise doses of drugs having a strong action; for example, vasoactive drugs. Unexpected and undetected halt of a syringe pump can lead to potentially life-threatening complications. We experienced a sudden halt in the movement of a syringe pump (Terufusion syringe pump; Terumo, Tokyo, Japan) in two patients while administering norepinephrine in the intensive care unit (ICU). ⋯ Once we had determined how a false setting of the syringe could occur without the syringe pump giving off an alarm from the onset, we collaborated with the Terumo Company to revise their current instruction manual to incorporate this as a warning. We also helped in the development of a new model, including a new safety feature that would prevent a false setting of the syringe from occurring at all. This new model was released in December 2003.

Effects of AM281, a cannabinoid antagonist, on circulatory deterioration and cytokine production in an endotoxin shock model: comparison with norepinephrine.
The purpose of this study was to examine the comparative effects of AM281, a cannabinoid antagonist, and norepinephrine (NE) on systemic hemodynamics, and renal and mesenteric artery blood flow in an endotoxin shock model. ⋯ Although NE and AM281 both prevented endotoxin-induced deterioration of systemic hemodynamics, AM281 yielded better preservation of mesenteric blood flow and attenuation of cytokine production than NE.

Review Meta AnalysisThe benefits of adding epidural analgesia to general anesthesia: a metaanalysis.
The purpose of this metaanalysis was to determine the benefits of postoperative epidural analgesia in patients operated on under general anesthesia. By searching the American National Library of Medicine's Pubmed database from 1966 to July 10, 2004, 70 studies were identified. These included 5402 patients, of which 2660 had had epidural analgesia. ⋯ It also reduces the first 24-h morphine consumption, OR = -13.62 mg (95%CI = -22.70, -4.54, P = 0.003), and improves the forced vital capacity (FVC), OR = 0.23 l (95%CI = 0.09, 0.37, P = 0.001) at 24 h. A thoracic epidural containing a local anesthetic reduces the incidence of renal failure: OR = 0.34 (95%CI = 0.14, 0.81, P = 0.01). Epidural analgesia may thus offer many advantages over other modes of postoperative analgesia.
