[Antibiotic prophylaxis in major surgery of the neck and head].

Twenty-two patients undergoing major head and neck surgery were included in a randomized trial to value the efficacy and side effects of parenteral short-term antibiotic prophylaxis of post-operative infections. Two different antibiotic regimens were compared: group A, ceftazidime i.v. (2 g) in three doses (half an hour before surgery, 8 and 16 hours, from the first dose); group B, netilmicin (100 mg) plus clindamycin (600 mg i.v.), following the same chronological schedule. Overall infection rate was 18% (4/22): all post-operative infections occurred in group A patients, including one case of wound infection and 3 mixed infections (wound infection associated with lung infection), with a significant reduction of post-operative infection rate in group B patients (p = 0.045; Fisher's exact test)

Selective transposition of the pectoralis major myocutaneous flap: An electromyographic evaluation

Although it has postulated that the segmental anatomy of the pectoralis major muscle should allow intact motor function to be preserved at the donor site after a myocutaneous island flap has been transposed, the functional outcome of this 'selective' harvesting technique has not been previously investigated. In this study the degree of innervation of the residual pectoralis major muscle on the chest after traditional (10 patients) and 'selective' (10 patients) pectoralis major myocutaneous flap transposition has been evaluated using postoperative electromyography. According to the data obtained, while an intact innervation of the external segment is maintained utilizing both techniques, it is impossible to preserve functional innervation of the remaining sternocostal strip medial to the donor site during a pectoralis major myocutaneous flap transposition, even after its 'selective' harvesting
