About this study

Official title: Cukurova University Faculty of Medicine

The aim of this study is to compare the risk factors and the incidence of delirium following orthopedic surgery under the general or regional anesthesia in elderly patients.

Read the detailed description

One hundred twenty elderly patients aged ≥65 years scheduled for total hip or knee arthroplasty and femur fracture surgery were enrolled into the study. Patients were allocated into two groups to receive regional anesthesia (group R, n=50) or general anesthesia (group G, n=70). Hemodynamic and blood parameters, potential risk factors of delirium including age, sex, duration of surgery, the type of anesthesia, coexisting disease, smoking and amount of drug used delirium tests (CAM and DRS-R-98), hospital stay and costs were recorded for all patients.

Being tested
propofol and esmeron(rokuronyum), marcaine and fentanyl
Keywords
Delirium, regional anesthesia, general anesthesia

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • propofol and esmeron(rokuronyum)Behavioural

    All patients were evaluated at postoperative 24th and 72th hours with laboratory tests including hemoglobin, sodium, potassium, BUN, creatinine, total protein, albumin and glucose values in blood samples and delirium tests (CAM and DRS-R-98).

  • marcaine and fentanylBehavioural

    All patients were evaluated at postoperative 24th and 72th hours with laboratory tests including hemoglobin, sodium, potassium, BUN, creatinine, total protein, albumin and glucose values in blood samples and delirium tests (CAM and DRS-R-98).

Study groupRoleWhat they receive
propofol and esmeron(rokuronyum)In group G, anesthesia was induced with iv propofol (2 mg.kg-1) and maintained with 2% sevoflurane in a mixture of 65 % nitrous oxide and 35 % oxygen with a total gas flow rate of 6 L min-1. Neuromuscular relaxation was induced with iv rocuronium (esmeron) (0.5 mg.kg-1). Intravenous infusion of 0.9% saline was administered at a volume of 5 mL/kg/h. Patients received morphine (0.1mg/kg) for postoperative analgesia 30 minutes before the end of the operation. Anesthesia was terminated and neuromuscular blockade was antagonized with neostigmine (0.05 mg.kg-1)and atropine sulphate (0.01 mg.kg-1).
Receives: Behavioral: propofol and esmeron(rokuronyum); Behavioral: marcaine and fentanyl
marcaine and fentanylWe inserted a 18-G Tuohy needle at the L3/L4 or L2/L3 intervertebral epidural space using an epidural loss of resistance technique and thus performed needle-through-needle technique for subarachnoid injection of 2 mL bupivacaine (marcaine)(0.5%) and fentanyl (25 mcg) by 27-G spinal needle. After subarachnoid injection, epidural catheter was advanced and fixed. At the end of the surgery 5 mL of bupivacaine 0.5% plus morphine (1 mg), adding to 4 mL saline was injected via epidural catheter for postoperative analgesia.Epidural catheter was removed at 24th hours
Receives: Behavioral: propofol and esmeron(rokuronyum); Behavioral: marcaine and fentanyl

What is being measured

The primary outcome is the main question the study is designed to answer.

    Measured: one year

Secondary outcomes (2)
  1. severity of delirium rated with the DRS-R-9

    Measured: one year

  2. length of hospital stay and costs.

    Measured: one year

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

the presence of postoperative delirium as defined by CAM criteria. (time frame: one year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
