What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Hydromorphone combined with ropivacaineDrug
Also called Quadratus lumbois block
1mg hydromorphone was added to 0.375% ropivacaine for a total of 30ml to perform quadrat block
RopivacaineDrug
Also called Quadratus lumbois block
A mixture of 0.375% ropivacaine for a total of 30ml was used for quadrate block
| Study group | Role | What they receive |
|---|---|---|
| Hydromorphone combined with ropivacaine | Experimental | The posterior quadrat block was performed by adding 1mg hydromorphone to 0.375% ropivacaine in a total of 30ml. Receives: Drug: Hydromorphone combined with ropivacaine |
| ropivacaine | Active comparator | A mixture of 0.375% ropivacaine for a total of 30ml was performed for posterior quadrate block. Receives: Drug: Ropivacaine |
What is being measured
The primary outcome is the main question the study is designed to answer.
Related indexes of anesthesia effect: pain after surgery, 6, 12, 18,24, 48h after surgery.
Visual analogue scale (VAS) was used to score the postoperative pain at 6,12,18,24,48h.The score ranges from 0 (no pain) to 10 (most severe pain). The change was equal to the score difference between the two groups at different observation time points (6,12,18,24,48h).
Measured: From the end of surgery until two days after surgery.
Related indexes of anesthesia effect: time of onset of anesthesia, duration of anesthesia maintenance.
The range of the effective time of anesthesia minus the start time of anesthesia and the maintenance time minus the start time of anesthesia are respectively.The unit of time is minutes.
Measured: From the start of anesthesia until two days after surgery.
Secondary outcomes (1)
The occurrence of postoperative adverse reactions.
The rates of postoperative nausea, vomiting and dizziness were compared between the two groups.
Measured: The operation ended two days after surgery.
