外傷(Trauma)シリーズ7 RESIDENT COURSE 解答 【症例 TR 33】

腹部大動脈刺創・後腹膜出血.Stab wound of aorta with massive hemorrhage.






図1で脾臓周囲に腹水が(※),図1〜図18(一部省略)で,大量の後腹膜腔内血腫(※)がある.出血量は,図9を平均的な部位とし体積計算すると6cm×12cm=72,スライス数は少なく見込んでも20だから72×20=1440,1440×8/10(10mmスライスに変換)で1000ml以上である.FASTの腹部エコー検査で容易に診断できたと思われ,CT検査は不要である.図6〜図14の△はextravasationであり,図12と図13の↑あたりが大動脈に最接近し出血部位と思われる.図1でIVCは虚脱し重度のhypovolemiaを意味する.白矢印は中心静脈カテーテル.手術で後腹膜腔に巨大な血腫を認め,下腸間膜動脈分岐部より末梢の腹部大動脈前壁に8mm大の刺創があり,活動性に出血しており止血した.

New concepts in the management of patients with penetrating abdominal wounds.
Ferrada R, Birolini D.

In the future, trauma research and care will have to become better, faster, and less expensive. Surgeons in the next millennium must be able to diagnose wounds, initiate correct procedures, and anticipate complications more accurately than before. Violent crime will not abate, nor will the proliferation of more powerful arms; these trends translate into graver traumatic wounds, giving the operating team less time to stabilize patients. Time management and team coordination are becoming key elements for patient survival, especially for patients with potentially fatal wounds, such as those to the heart. The authors have reduced the time from arrival to surgery to a few minutes. The keys to this feat are readiness, team coordination, and high morale. Financial resources will continue to be limited and allocated on a need-first basis. In the future, trauma centers will compete for dwindling funds. Technology is and always will be just a tool, whereas qualified trauma surgeons are irreplaceable, much more so than in any other surgical specialty. Observation, diagnosis, and surgery are, of course, greatly facilitated by ever-evolving technology, but since the time of Hippocrates, split-second decisions can ultimately be made only by the caregiver in the white smock. Trauma surgeons in the next millennium will have to exercise judgment based on knowledge, surgical skills, and contact with patients. To err is human, but in surgery, errors often cause death, and no machine will ever relieve surgeons of that burden. PMID: 10625982
