General Anesthesia, Testosterone, BIS
Conditions
Brief summary
The aim of this observational study is to learn the effects of hormone therapy (testosterone) applied in micropenis hypospadias surgery on the depth of anesthesia under general anesthesia. The main question it aims to answer is: The effect of testosterone therapy on the depth of general anesthesia. Based on these, to comment on the depth of anesthesia of patients who have just started using testosterone for sex change. To follow the depth of anesthesia of patients who have undergone hypospadias surgery with BIS monitoring and to record respiratory parameters under general anesthesia.
Interventions
DEVICEBispectral index (BIS)
The bispectral index (BIS) monitor is a quantitative electroencephalographic (EEG) device that is widely used to assess the hypnotic component of anaesthesia, especially when neuromuscular blocking drugs are used. If necessary, it may be necessary to increase or decrease MAC (minimum alveolar concentration) in the testosterone group according to the BIS monitoring value.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| BIS values | 4 months | in addition to monitoring the MAC and vital values in order to monitor the depth of anesthesia, BIS monitoring values, which are a special EEG parameter and can be continuously monitored throughout the surgery, also provide better quality results. The use of the BIS monitor reduces the incidence of awareness under anesthesia. The fact that the procedure is non-invasive is an advantage in terms of use. Hypospadias often requires surgical intervention. Before this surgical intervention, pediatric surgeons perform hormone (testosterone) treatment (IM) in patients with micropenis to temporarily enlarge the penis size, which affects the success of the surgery. It is usually applied intramuscularly one week before the surgery in a pediatric surgery clinic. Some studies have reported that anesthetic requirements change with testosterone changes (to provide sufficient depth of anesthesia with changes in the depth of anesthesia). |

| sex change and anesthesia | 4 months | Comment on the initial anesthesia of adult patients who have to use testosterone after sex change |
