Clinical Trial – Effect of Intravenous Magnesium on Post-spinal Fentanyl Induced Pruritus Incidence

Introduction: Adding opioids to local anesthetic solutions leads to enhanced anesthesia and
provide postoperative analgesia. Intrathecaly injected opioids have some side effects,
though. One of them is pruritus. Objective: We designed a randomized, double‐blinded,
placebo‐controlled study to evaluate prophylactic impact of continuous IV Magnesium 10mg/kg
over 30 minutes on intrathecal fentanyl‐induced pruritus start at the end of the operation.

Methods: ASA I‐II Patient’s candidate for orthopedic operations under spinal anesthesia
(10‐15mg hyperbaric bupivacaine and 25 µg fentanyl intrathecal) and will be divided randomly
into two groups:

Control group (Placebo group): bolus 100 ml nacl 0.9% at end of surgery Study group (Mg ++
group): (continuous IV Magnesium 10mg/kg in 100 ml Nacl0.9% over 30 minutes at end of
surgery).

Study outcome:

1. Hemodynamics: Systolic blood pressure, Mean arterial blood pressure, pulse rate, O2
saturation will be recorded in 5 min,10 min,30 min,60 min and every one hour till 6
hours after the operation.

2. Pruritus Patients were asked about existence (present=1,no=0), severity (mild=1,
modret=2, sever =3) and site of pruritus (Face(trigeminal) =1, neuroaxial(dermatome)=2),
1,2,4, and 6 hours after operation. Incidence of pruritus total group incidence %.

3. The incidence of PONV.

Clinical Trial – Hyperbaric Oxygen Therapy After Stroke – PILOT

The goal of this pilot study is to establish more information about hyperbaric oxygen therapy
for this group of patients, and give us more information of how to initiate the best possible
main study. Can we find any indications that support the use of this therapy for patients
suffering from chronic disability after cerebral infarction? Can we improve physical and
cognitive function.

The AC133 antigen is a novel antigen selectively expressed on a subset of CD34+ cells in human fetal liver, bone marrow, and blood as demonstrated by flow cytometric analyses. In this study, we have further assessed the expression of AC133 on CD34+ cells in hemopoietic samples and found that there was a highly significant difference between normal bone marrow and cord blood versus aphereses (p <0.0001) but not between bone marrow and cord blood. Most of the clonogenic cells (67%) were contained in the CD34+AC133+ fraction. Compared with cultures of the CD34+AC133- cells, generation of progenitor cells in long-term culture on bone marrow stroma was consistently 10- to 100-fold higher in cultures initiated with CD34+AC133+ cells and was maintained for the 8-10 weeks of culture.
