Performance of the ratio of posterior complex length to depth measured by ultrasound as a predictor of difficult spinal anesthesia for elective cesarean delivery: a prospective cohort study.

Purpose: Ultrasound view of the interlaminar structure is likely to be associated with difficult spinal anesthesia (DSA), and a poor ultrasound view which cannot show the anterior and posterior complex predicts a difficult spinal technique. As our target site is the posterior complex, this study aimed to assess whether the ratio of posterior complex length to depth measured by ultrasound can predict DSA in cesarean delivery.

Methods: Four anesthesiologists with 1-2 years of experience located and marked the puncture interspace using a traditional surface landmark.

Low-dose intranasal dexmedetomidine premedication improves epidural labor analgesia onset and reduces procedural pain on epidural puncture: a prospective randomized double-blind clinical study.

Background: Epidural labor analgesia is a safe and effective method of pain management during labor with the drawbacks of delayed onset and maternal distress during epidural puncture. This study aimed to determine whether pretreatment with intranasal low-dose dexmedetomidine effectively shortens the onset of analgesia and reduces procedural pain.

Methods: In this prospective, randomized double-blind trial, nulliparous patients were randomly assigned to either the intranasal dexmedetomidine group or the control group.

Dural puncture epidural technique provides better anesthesia quality in repeat cesarean delivery than epidural technique: Randomized controlled study.

Background: Repeat cesarean deliverys involve a longer surgery and more severe visceral traction than primary cesarean deliverys. The dural puncture epidural (DPE) technique provides faster and more effective analgesia for labor, but there is no sufficient evidence to indicate whether it is suitable for parturients undergoing repeat cesarean delivery.

Aim: To determine the efficacy and safety of the DPE anesthesia technique in patients undergoing repeat cesarean delivery.

A Randomized Clinical Trial Comparing Different Concentrations of Chloroprocaine with Lidocaine for Activating Epidural Analgesia During Labor.

Purpose: This study aimed to explore the efficacy and safety of chloroprocaine for activating labor analgesia and the optimal concentration compared to lidocaine.

Patients And Methods: Ninety-six nulliparous parturients were randomly assigned to three groups: LD group, patients received the conventional initial dose of 6 mL of 1% lidocaine; CP1.5 group, patients received 6 mL of 1.

Is antibiotics use really associated with increased risk of colorectal cancer? An updated systematic review and meta-analysis of observational studies.

Purpose: The association between antibiotics and colorectal cancer (CRC) risk has drawn increasing attention but remains controversial. This study was performed to clarify the association.

Methods: A systematic review and meta-analysis was performed on seven electronic databases.
