Observational StudyProspective Observational Study of Patient-Controlled Intrathecal Analgesia: Impact on Cancer-Associated Symptoms, Breakthrough Pain Control, and Patient Satisfaction.
Although data exist for the efficacy of intrathecal therapy (ITT), there are no prospective data on patient-controlled intrathecal analgesia (PCIA) in refractory cancer pain. This study examines the effect of PCIA on cancer symptom scores, patient satisfaction, and analgesic efficacy with an emphasis on breakthrough pain (BTP). ⋯ In patients with poorly controlled cancer pain, PCIA is associated with improved pain control, improved cancer-related symptoms, and high satisfaction. Compared with conventional BTP regimens, PCIA provides superior analgesia and a 3-fold faster onset of action.

Pneumoperitoneum Does Not Influence Spread of Local Anesthetics in Midaxillary Approach Transversus Abdominis Plane Block: A Descriptive Cadaver Study.
The transversus abdominis plane (TAP) block can be used as part of a multimodal analgesia protocol after abdominal surgery. This study investigated whether a pneumoperitoneum during abdominal surgery influences the spread of local anesthetics. ⋯ The stretch of the abdominal wall caused by the insufflation of the abdomen does not influence the spread of dye in the abdominal wall. Because of the absence of posterior spread, regardless of the timing of a midaxillary ultrasound-guided approach, we believe that a posterior approach should be chosen if posterior spread is desired.
