Randomized Controlled Trial Clinical TrialPrevention of hypotension after spinal anesthesia for cesarean section: dextran 40 versus lactated Ringer's solution.
This study was designed to compare the efficacy of 10% dextran 40 with lactated Ringer's (LR) solution in reducing the incidence and severity of hypotension after spinal anesthesia for Cesarean section. ⋯ We concluded that 500 ml of dextran 40 is more effective than 1000 ml of lactated Ringer's solution in reducing the incidence of hypotension induced by spinal anesthesia.

Randomized Controlled Trial Clinical TrialLow dose ketamine and midazolam as supplements for spinal anesthesia.
Low dose ketamine and midazolam together were used as supplements during spinal anesthesia to provide analgesia for insertion of spinal needle and intraoperative sedation. ⋯ The use of low dose ketamine together with midazolam as supplement for spinal anesthesia is helpful in anesthetic practice.

Randomized Controlled Trial Clinical TrialSoftened endothracheal tube reduces the incidence and severity of epistaxis following nasotracheal intubation.
Many complications were reported to be related with nasotracheal intubation. Various chemical or mechanical techniques have been proposed to decrease hemorrhage and trauma associated with nasotracheal intubation but the results remain controversial. We conducted a prospective, randomized, single-blind study to elucidate the effect of an endotracheal tube softened with warm water before use on the incidence and severity of epistaxis following nasotracheal intubation. ⋯ In conclusion, our study shows that using an endotracheal tube softened by warm water could reduce the incidence and severity of epistaxis during the act of nasotracheal intubation. It is an effective way and worth a try.

Randomized Controlled Trial Comparative Study Clinical TrialComparison of the cuffed oropharyngeal airway and laryngeal mask airway in spontaneous breathing anesthesia.
The cuffed oropharyngeal airway (COPA) is a modified Guedel airway with a cuff at its distal end and a standard 15 mm connector at its proximal end. This study was performed to determine if the COPA would offer any advantage over the laryngeal mask airway (LMA). ⋯ We demonstrated that the COPA could be easily inserted without the need of muscle relaxants in most patients. But the COPA needed airway intervention to provide an effective airway in most patients. Compared with the LMA, the COPA caused less stimulation than the LMA.

Randomized Controlled Trial Clinical TrialSubarachnoid fentanyl with diluted small-dose bupivacaine for cesarean section delivery.
The use of neuraxial opioid was very popular in recent years, and they may augment the analgesia produced by local anesthetic through direct binding with the spinal opioid receptors. Hemodynamic stability is very important during Cesarean section. Theoretically, the reduction of local anesthetic by addition of fentanyl would provide better hemodynamic stability and good anesthetic status. ⋯ The combination of small-dose bupivacaine with fentanyl could provide more stable hemodynamic status, longer postoperative analgesia, and lower incidence of shivering. The incidence of pruritus in group M + F was high, but it was usually mild.
