Unilateral Epidural Blockade for Lower Limb Fracture Surgery: Parasagittal Epidural Versus Midline Epidural Anesthesia

The effect of lemon inhalation aromatherapy on pain, nausea, as well as vomiting and neurovascular assessment in patients for lower extremity fracture surgery: a randomized trial

BACKGROUND

Complementary and integrative medicine may be effective for postoperative outcomes. This study aimed to determine the effect of lemon inhalation aromatherapy on pain, nausea, and vomiting and neurovascular assessment in patients for lower extremity fracture surgery.

METHODS

This is a randomized clinical trial study. Ninety patients who had undergone lower extremity fracture surgery were randomly assigned to the intervention (lemon aromatherapy) and control groups. Lemon aromatherapy was started in the morning of the surgery and extended at two-hour intervals until the end of the surgery, in the recovery room, and 16 h after surgery. Numerical pain and nausea and vomiting scales, the Rhodes Index of Nausea, Vomiting, and Retching, and the WACHS Neurovascular Observation Chart were used to assess the outcomes before and after the intervention (in the recovery room and 4, 8, 12, and 16 h post-surgery). The data were analyzed using the Wilcoxon test, ANCOVA, and Repeated Measure ANCOVA.

RESULTS

A significant difference was observed between the groups in terms of the intensity of pain (P < 0.001) and nausea and vomiting (P = 0.001) during the study period. Moreover, a significant difference was found between groups as to the frequency and severity of nausea, vomiting, and retching. The amount and duration of postoperative vomiting and nausea were significantly lower in the intervention group compared to the control group. In addition, lemon inhalation aromatherapy decreased the frequency of anti-emetic drug administration in the recovery room (P = 0.04) and 16 h post-surgery (P = 0.03).

CONCLUSIONS

This study indicated that aromatherapy reduced pain intensity, postoperative nausea, vomiting, and retching, as well as the incidence of anti-emetic drug administration. Therefore, using lemon inhalation aromatherapy to relieve pain and reduce nausea and vomiting is suggested for lower extremity fracture patients who have undergone surgery.

TRIAL REGISTRATION

This study was registered in the Iranian Registry of Clinical Trail (Number = 57,331, IRCT20130616013690N10, approved 24/07/2021) ( https://www.irct.ir/trial/57331 ).

Combination of Epidural Blockade and Parecoxib in Enhanced Recovery After Gastrointestinal Surgery

OBJECTIVE

To investigation effects of the combination use of epidural blockade and parecoxib in postoperative recovery of colorectal cancer (CRC) patients.

METHODS

The present prospective single-blinded study included 186 CRC patients who received radical resection during April 2016 to December 2017. All patients were randomized into 3 different groups, the epidural blockade group, the combined-group with both epidural blockade and pre-intravenous injection of parecoxib, and the control group. The mean operative time, bleeding volume, the first out of bed activity time and hospital stay time were recorded. The mini-mental state examination (MMSE) score and Ramsay score were measured for cognitive function and the Visual Analog Score (VAS) was determined for the pain condition.

RESULTS

The surgery time for the control group was significantly shorter than the other 2 groups (P < 0.05). The VAS scores were significantly lower in both the combined group and the epidural blockade group when compared with the control group and were dramatically lower in the combined group than the others 2 groups (all P < 0.05). The first out of bed activity time and hospital stay time were the shortest in the combined group, and the control group had the longest time (all P < 0.05). Both the Ramsay and MMSE scores were the highest in the combination group than other groups (all P < 0.05) and no significant difference was observed between the epidural blockade group and the control.

CONCLUSION

The combination of epidural blockade and parecoxib could enhance the recovery process, as well as reduce the pain for the CRC patients.
