熱布による腰背部温罨法が腸音に及ぼす影響

The Effect on Bowel Sounds of Very Hot Compresses Applied to the Lumber Region

要旨

　腹満や便秘に対し，経験上有効といわれている熱布による腰背部温罨法の，腸管の動きに対する影響と，局所の皮膚に対する影響を明らかにする目的で，実験研究を行った．8名の健康な女性（27～47才）に，熱布による温罨法を施行し，以下のような結果を得た．

1）腸音は施行直後に1.7倍に増加し，施行前に対し，有意差が認められた．

2）貼用部の皮膚温は，41.1-43.1度まで一過性に上昇したが，火傷は生じなかった．

3）背部の血流および上腕部の血流は，施行前に比べ1.4倍になり，全身が暖まった．

4）施行前後で、体温，脈拍，血圧に変動は認められなかった．

　これらの結果から，熱布による腰背部温罨法は，腸管の動きを促進し，便秘や腹満の解消をはかる看護技術となりうることが示唆された．

Abstract

　In Japan, very hot moist compresses applied to the lumber region have been used to promote intestinal movement and flatus or defecation. This skill was based on empirical knowledge.

　One of the purposes of this study is to make clear the effect of very hot compresses on intestinal movement.t The other purpose is o prove the safety of the skin where very hot compresses applied.

　The sample consisted of 8 healthy female volunteers, ranging in age from 27 to 47 with a mean age of 37.4. A very hot compress was applied to the lumber region for 10 minutes.

　The results were as follows :

1) Bowel sounds immediately after hot compresses increased 1.7times compared with bowel sounds before the hot compresses.

2) Skin temperature of the back increased to 41.1-43.1 degrees centigrade under the hot compresses, then decreased rapidly.

3) Blood flow to the back during hot compresses, increased to156%. Blood flow to the upper arm also increased.

4) Body temperature, pulse rate and blood pressure were not remarkably changed by the hot compresses.

　The results of the experiments show that very hot compresses applied to the lumber region affect intestinal movement. And the results suggest that a very hot compress is a useful nursing skill to promote flatus or defecation.
