Brief Summary
During general anesthesia, intravenous (IV) medications can disrupt the patient's comfort by causing a pain sensation or a withdrawal response in the heart. Propofol and rocuronium are among the most common causes of this condition. In recent years, the use of ultrasonography (USG) in anesthesia has become widespread with the rapid advancement of technology. The use of the patient's head is a non invasive method. This study is aimed to evaluate whether the size of the venous diameter assessed by ultrasonography in our study is an effect on pain and withdrawal response after drug injections.

Outcome Measures
Primary Outcomes (1)
The injection pain due to propofol
Pain will be recorded and graded using a 4-point scale (none, mild, moderate, or severe).
6 month
Secondary Outcomes (1)
The withdrawal movement due to rocuronium
6 month
Study Arms (2)
Group 1
Venous diameter measurements were made via the USG in the hand dorsum. Transverse venous diameter ≤2mm was defined group 1. Anesthesia induction drugs were all treated in the same order and dose. Pain score, withdrawal movement score and hemodynamic response was recorded.
Group 2
Venous diameter measurements were made via the USG in the hand dorsum.Transverse venous diameter \>2mm was defined group 2.Anesthesia induction drugs were all treated in the same order and dose. Pain score, withdrawal movement score and hemodynamic response was recorded.
Interventions
Withdrawal movements 1. no movement response 2. movement limited to the wrist 3. movement limited to the elbow/shoulder, 4. generalized movement response.
Hemodynamic data were recorded in the patients taken in the operation room. (T0). Hemodynamic values (T1) measured 1 minute after administration of intravenous propofol were recorded. Hemodynamic values (T2) measured 1 minute after administration of intravenous rocuronium were recorded. Hemodynamic values (T3) measured 1 minute after administration of endotracheal intubation were recorded.
Eligibility Criteria
The study was conducted on 145 patients aged 17- 70 years of ASA (American Society of Anesthesiologists) physical status I- II who were to undergo various elective operations. None of the patients was premedicated before the operation. Venous diameter measurements were performed in preoperative room via USG.The patients were monitored with three derivation electrocardiogram, non- invasive arterial pressure, and pulse oximeter.
You may qualify if:
- years of ASA (American society of anesthesiology) physical status I- II who were to undergo various elective operations
You may not qualify if:
- Rheumatologic disease Peripheric vascular disease Vasculitis Patients with chronic pain syndrome, Patients with neurologic deficits, Patients with thrombophlebitis, Patients with difficult venous access, Patients with allergy
