Study summary

Anorectal problems, such as hemorrhoids, fistula, fissures, Etc., often require surgical treatment. Patients often have postoperative pain after these surgeries, which increases discomfort and hospital length of stay. The efficacy of oral non-opioids in the treatment of such pain is poor. Hydromorphone is an opioid analgesic commonly used orally or intravenously for postoperative pain management. We designed this trial to investigate the efficacy and safety of intrathecal (delivery directly to the spinal cord during spinal anesthesia) single dose hydromorphone versus intrathecal placebo in treating postoperative pain among human subjects after anorectal surgery, but also the recovery of postoperative motor capacity in these human subjects.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

ASA physical status

The anaesthetists’ scale of health before surgery: I is healthy, II has a mild illness that is under control, III a severe one, IV a severe illness that is a constant threat to life. V and VI are used for the critically ill and for organ donors.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

What researchers measure

Primary outcomes

  1. Numerical Rating Scale Pain Scores (NRS score for pain)

    NRS for pain (0-10) with movement 12 hours after spinal administration

    Time frame: Time of spinal injection finished will be noted as time: "0". NRS, with movement 12 hours, will be collected by patient interview at 12 hours after spinal administration.

Secondary outcomes

  1. NRS score at rest/with movement

    NRS score for pain (0-10) with movement, and at rest.

    Time frame: Time of spinal injection finished will be noted as time: "0". NRS, with movement or at rest, will be collected by patient interview at 1, 3, 6, 12, 24 and 36 hours after spinal administration.

  2. Highest pain NRS (0-10) in previous 12 hours

    NRS score for pain (0-10) with movement or at rest and the time.

    Time frame: At 12 hours after spinal administration.

  3. Severity and incidence of any opioid-related complication at each time point

    Including: nausea, vomiting, constipation, diarrhea, itching, dry mouth, dizziness, numbness, depression, anxiety, fever, skin rash, urinary retention, Etc.

    Time frame: All data will be collected by patient interview at 1, 3, 6, 12, 24 and 36 hours after spinal administration.

  4. Total non-opioid analgesic consumption

    Total non-opioid analgesic consumption at 12, 24 and 36 hours after spinal administration, mainly intravenous parecoxib/ketorolac/flurbiprofen injection dosage.

    Time frame: All data will be collected by patient interview at 12, 24 and 36 hours after spinal administration.

  5. Recovery of lower extremity strength.

    Time required to the recovery of casual movement of the lower extremities

    Time frame: Data will be collected by patient interview at 12 hours after spinal administration.

  6. Quality of Recovery Scale (QoR)
