We identified 45 patients (31 and 14 in the DEX and NLA groups, respectively) with a mean age of 69.0 years. The two groups had comparable characteristics, such as age, sex, body mass index, the American Society of Anesthesiologists Physical Status, analgesics used in the clinic, comorbidities, history of smoking, and the duration of anesthesia. The DEX group received a significantly lower fentanyl dose during surgery (126 ± 14 vs. 193 ± 21 µg, mean ± standard deviation, P = 0.014) and exhibited a significantly lower incidence of PONV (1 vs.
Minimally invasive epiduroscopy may be an effective treatment for such conditions;11 therefore, the number of epiduroscopy procedures performed is currently increasing worldwide.12, 13 This procedure consists of observation, washing, irrigation, lysis of the adhesion in the epidural space under direct visual observation, and direct drug administration to the affected part of the spinal canal.12–14 However, anesthesia is required to alleviate pain during the lysis of the adhesions in the epidural space.15 Thus, monitored anesthesia care (MAC) should be used to provide anesthesia during epiduroscopy.16–18
The statistical analysis was designed to compare the DEX and NLA groups. Continuous parameters were expressed as means ± standard deviations (SD) and independent t-tests were conducted to compare the groups. Categorical variables were expressed as frequencies and percentages, and
The values in Table 1 and 2 have been changed as follows:
Comparison of patient characteristics, American Society of Anesthesiologists (ASA) physical status classification system, comorbidities, and analgesic agents between the DEX and NLA groups.
ASA, The American Society of Anesthesiologists; DEX group, dexmedetomidine plus fentanyl; NLA group, droperidol plus fentanyl; BMI, body-mass index; NSAIDs, Nonsteroidal Anti-inflammatory Drugs; SD, standard deviation.
Comparison of intraoperative drugs between the DEX and NLA groups.
DEX group, dexmedetomidine plus fentanyl; NLA group, droperidol plus fentanyl; SD, standard deviation.
A comparison of the incidence of PONV and the dose of fentanyl during surgery between the DEX and NLA groups is shown in Figure 2. The presence or absence of PONV was determined based on the history of receiving an antiemetic (metoclopramide or domperidone), which was noted in significantly fewer patients in the DEX group than in the NLA group (1 vs.
Figure 2 has been changed as follows:
