DHEA is a naturally occurring androgen produced by the adrenal glands. It is abundantly found in plasma and brain tissue and is the precursor of many hormones produced by the adrenals. DHEA seems to alleviate some of the effects of aging, such as fatigue and muscle weakness. Levels of DHEA may be lower in depressed patients, while supplementation with DHEA may reduce symptoms. However, since DHEA is a hormone, you should not take it without having your doctor check your blood level of the hormone. Also check with your physician before adding it to your diet if you are on an antidepressant, a thyroid medication, insulin, or estrogen.
The caudal approach to the epidural space involves the use of a Tuohy needle, an intravenous catheter, or a hypodermic needle to puncture the sacrococcygeal membrane . Injecting local anaesthetic at this level can result in analgesia and/or anaesthesia of the perineum and groin areas. The caudal epidural technique is often used in infants and children undergoing surgery involving the groin, pelvis or lower extremities. In this population, caudal epidural analgesia is usually combined with general anaesthesia since most children do not tolerate surgery when regional anaesthesia is employed as the sole modality.
