At this point 20 c.c. of the same solution are injected close to the bone. The needle is then drawn back and passed between the rectum and the coccyx, where a last injection is made of 5 c.c. of the same solution. The injections are repeated on the opposite side using a total of about 100 c.c. of the 1 per cent, solution. If the operator feels that he should control the position of the needle, especially in making the deep injection at the level of the first sacral foramen, a finger is placed in the rectum and only removed when the anesthetic procedure has been completed, avoiding by this precaution the possible contamination of the needle. For the purpose of refilling the syringe the care of the instruments is left to an assistant, But the author agrees with Braun that it is not necessary to place a finger in the rectum as a guide for the needle, "as the empty bowel is not easily injured and evades the needle." Practical Considerations.--The anesthesia produced by the presacral block is said to be similar to that resulting from the transsacral block, since the nerves blocked are the same, apart from the fact that the posterior primary divisions of the sacral nerves are not reached by the presacral injections. Differences, however, exist in the quality of the anesthesia and in its duration, when comparing the clinical results obtained with both procedures. In the transsacral block the increased pressure on the nerves due to the retention of the anesthetic fluid in the foramen, which is a partially closed space, establishes favorable conditions for rapid anesthesia.
