Any landmark-based regional anaesthetic technique raises two important issues. The first is the accuracy of placement of the needle and thus the local anaesthetic in a 'blind' technique and the second is the potential for damage to adjacent structures. We designed a prospective, blinded study in an adult general surgical population to evaluate with ultrasound the placement of the needle tip and local anaesthetic during transversus abdominis plane (TAP) blocks using the landmark-based 'double-pop' technique. ⋯ We conclude that the needle and local anaesthetic placement using the standard landmark-based approach to the TAP block is inaccurate, and the incidence of peritoneal placement is unacceptably high.

An analysis of perioperative factors that were independently associated with survival up to 1000 days after scheduled colorectal adenocarcinoma resections in 314 patients. ⋯ Immediate perioperative care may have prolonged effects on postoperative survival. Specialized preoperative assessment clinics may reduce mortality after colorectal surgery.
