Pleural Trocar

The Trocar point is in the 7-8th intercostal space of the shoulder line or the posterior line, the 6th to 7th intercostal space of the middle line, and the 5th to 6th intercostal space of the front line. Gas can be extracted to treat pneumothorax, inflammatory exudate in the pleural cavity can also be withdrawn, or drugs can be injected to treat pleurisy and relieve respiratory distress. The liquid can be extracted for laboratory and bacterial culture.

Pericardium

Use the chest needle to puncture the pericardial cavity from the 5-6 rib space in the midline of the left clavicle. Pull out the fluid and relieve the pressure on the heart. When replacing the needle tube during operation, the tube should be clamped to prevent air from entering. You can also inject antibiotics into the pericardium for treatment.

Abdominal body cavity and organ puncture

Abdominal puncture

1 cm from the midpoint of the umbilical to the pubic symphysis, and 1 to 1.5 cm apart from the abdominal cavity. It is used to diagnose ascites of unknown cause and release ascites to relieve breathing difficulties. It can also be injected into the abdominal cavity.

Liver puncture

Can be used for biopsy (see liver biopsy).

Renal Trocar

Use the 9th and 10th lumbar needles to puncture the kidneys at the lower edge of the 12th rib, 6 to 6.5 cm beside the midline of the back, and take the living tissue for examination. For unclear primary glomerulonephritis, pyelonephritis, nephrotic syndrome, multiple myeloma involving kidney, kidney tumor, kidney sclerosis, etc. Patients with muscle tendencies, high blood pressure and peri-renal abscess, kidney tuberculosis should avoid puncture.

Bladder Trocar

Puncture the bladder above the midpoint of the pubic bone for patients with urinary retention due to prostatic hypertrophy and catheter failure.

Palace Trocar

Puncture the uterus above the pubic bone and remove the amniotic fluid to determine the lecithin/nitramine ratio. It is helpful to determine the fetal lung maturity, whether there is hyaline membrane disease after birth, and the best time to predict pregnancy and the best way to pregnancy.
