Duration of effect of the saddle block
The duration of the saddle block depends on several factors. These include the medication chosen, the dose and also some individual factors such as the speed of degradation of the local anesthetics. For longer procedures, a catheter can also be left in the spinal canal so that new doses of local anesthetic can be administered as needed. Depending on the medication, the effect usually wears off after about two hours.
Advantages of a saddle block
The real saddle block leads to a very localized anesthesia and affects only a few regions which are to be anesthetized. This advantage can be used optimally in obstetrics.The sensitive areas of the pelvic floor muscles and perineum are anaesthetized, while the uterine muscles are not restricted. For this reason, a natural birth can be relatively painless. An advantage of all regional anaesthetic procedures compared to general anaesthesia is the low effect on the whole body and thus a lower risk of complications.
Side effects of a saddle block
Side effects, in contrast to risks, are calculated possible effects of the drug or the intervention, which occur relatively frequently. The draining of spinal fluid can cause tension headaches after the procedure, which should subside after a few days. A hematoma (bruise) at the injection site may also occur and in some cases may lead to short-term neurological consequences. The local anesthetic may also cause reddening of the skin and local allergic reactions at the injection site.
Risks of a saddle block
The risks of saddle block anaesthesia are very similar to those of classic spinal anaesthesia. Injury to nerves can cause permanent damage and discomfort. Another risk is the injection of local anaesthetic into a blood vessel, as this has severe effects on the cardiovascular system and the central nervous system.
Allergic shock is also a possible risk when local anaesthetics are administered. Furthermore, germs can enter the spinal canal and lead to meningitis or abscesses (accumulations of pus). Overall, the risks can be considered weaker than those associated with general anesthesia. In the following article you can read more about this topic: Complications of spinal anesthesia
