まとめ
産後の直後の管結束は,重大な吸入リスクが伴う. 胃の超音波検査は,従来の断食ガイドラインは,産後早期の胃の状態を正確に反映しない可能性があるため,このリスクを効果的に評価します.
科学分野:
- 産婦人科と産婦人科を担当しています.
- アネステシオロジー アネステシオロジー
- メディカルイマージング (医学イメージング)
背景:
- ACOGは,分娩後の管結節手術を緊急に推奨しています.
- 産後初期にアスピレーションリスクの評価は極めて重要です.
- 伝統的な断食基準は,出産後の信頼性がないかもしれません.
研究 の 目的:
- 胃の超音波を用いて産後の吸血リスクを評価する.
- 超音波検査の結果と,アメリカ麻酔学会 (American Society of Anesthesiologists) の断食基準を比較するために.
主な方法:
- 54人の女性を対象とした前向きな研究で,陰道出産後の女性を対象としたものです.
- 胃の超音波検査は,出産後1時間後に実施しました.
- 質的および定量的超音波パラメータに基づいて定義された高吸入リスク.
主要な成果:
- 女性の46.3%が,超音波による高吸入リスクを示した.
- 27.8%が断食基準を満たしたが,依然として高リスクの胃の内容物があった.
- 前回の摂取からの平均時間: 2.0h (透明な液体), 15.2h (固体).
結論:
- 産後の直後の管結束は,相当なアスピレーションリスクをもたらす.
- 胃の超音波検査は,産後早期の処置において,吸入リスク評価のために推奨されます.
- タイムベースの断食基準は,産後アスピレーションリスクを正確に評価するには不十分です.

Endoscopic Studies II: Thoracocentesis
Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...

Assessment of the Abdomen I: Inspection and Auscultation
Introduction
The abdominal examination is a cornerstone of clinical medicine, serving as a critical tool in diagnosing various gastrointestinal (GI) diseases. It involves a systematic approach that includes inspection and auscultation, each with distinct yet complementary roles in assessing the abdomen. This article will delve into these two primary methods healthcare professionals use to examine the abdomen.
Inspection of the Abdomen
The first step in any abdominal examination is inspection.

Endoscopic Procedures I: Esophagogastroduodenoscopy
An Esophagogastroduodenoscopy (EGD) is a diagnostic procedure in which an endoscopist uses a flexible, lighted endoscope to visualize the upper gastrointestinal (GI) tract. The procedure includes visualizing the oropharynx, esophagus, stomach, and the first part of the small intestine, the duodenum.
During an EGD, the endoscope can be used to:

Upper GI Series: Barium Swallow
The Barium Swallow Study, or a Barium Esophagogram, is a diagnostic imaging method used to visualize the upper gastrointestinal (GI) tract, including the esophagus, stomach, and small intestine. It employs barium sulfate, a radiopaque contrast material, to provide clear images of the upper digestive system, helping to identify abnormalities, diseases, or structural issues.
Purpose and Procedure
Patients undergoing this procedure ingest a liquid containing barium sulfate with a chalky...

Lower GI Series: Barium Enema
A Barium Enema, or a lower GI series, is a specialized radiographic examination designed to visualize the lower gastrointestinal tract, specifically the colon and rectum. This procedure is instrumental in diagnosing various conditions such as colorectal cancer, polyps, diverticulosis, and inflammatory bowel disease.
Procedure Details
The examination begins by inserting a lubricated rectal tube into the patient's rectum to administer a radiopaque barium solution. The barium flow is carefully...
