Patients in the intensive care unit seldom have mechanical small-bowel obstruction, and obstruction due to medication bezoars is even less common. A 65-year-old woman, in the intensive care unit because of septic shock and acute renal failure, had a small-bowel obstruction due to Amphojel concretions. Obstruction from such a cause may be prevented by including non-constipating antacids, stool softeners or sorbitol. Aggressive use of H2-antagonists to prevent gastrointestinal bleeding in septic patients will reduce the need for orally administered antacids. When obstruction occurs due to antacid concretions, it may be relieved by passing a long intestinal tube, by giving enemas for colonic obstruction or by operation.
重症监护病房的患者很少发生机械性小肠梗阻,因药物性胃石导致的梗阻更为罕见。一名65岁女性因感染性休克和急性肾衰竭入住重症监护病房,发生了因氢氧化铝凝胶结块导致的小肠梗阻。通过使用不引起便秘的抗酸剂、大便软化剂或山梨醇可预防由此类原因导致的梗阻。积极使用H2拮抗剂预防感染患者的胃肠道出血将减少口服抗酸剂的需求。当因抗酸剂结块发生梗阻时,可通过插入长肠管、对结肠梗阻进行灌肠或手术来缓解。
