NOTE: Duraclon┬« (epidural clonidine) is not recommended for obstetrical, post-partum, or peri-operative pain management. The risk of hemodynamic instability, especially hypotension and bradycardia, from epidural clonidine may be unacceptable in these patients. However, in a rare obstetrical, post-partum or peri-operative patient, potential benefits may outweigh the possible risks.
Duraclon (clonidine hydrochloride injection) is a centrally-acting analgesic solution for use in continuous epidural infusion devices.
Clonidine Hydrochloride, USP, is an imidazoline derivative and exists as a mesomeric compound.
Duraclon is indicated in combination with opiates for the treatment of severe pain in cancer patients that is not adequately relieved by opioid analgesics alone. Epidural clonidine is more likely to be effective in patients with neuropathic pain than somatic or visceral pain (see
The safety of this drug product has only been established in a highly selected group of cancer patients, and only after an adequate trial of opioid analgesia. Other use is of unproven safety and is not recommended. In a rare patient, the potential benefits may outweigh the known risks (see

Safety of Clonidine in Infants With Hypoxic Ischemic Encephalopathy During Therapeutic Hypothermia [Not yet recruiting]
This research is being done to find out the safety of the investigational study
drug,clonidine, in infants who are undergoing whole body cooling for the treatment of
hypoxic ischemic encephalopathy (HIE). HIE is the damage that occurs to the cells of the
central nervous system (brain and spinal cord) as a result of decreased oxygen supply and
blood flow to the fetus due to perinatal asphyxia (inadequate oxygen to the baby during the
birth process). HIE is a significant cause of morbidity and mortality in infants. The only
known and effective treatment for HIE is therapeutic hypothermia or whole body cooling for72
hours. During the cooling process babies get agitated, shiver and are uncomfortable. To
treat these side effects sedative-analgesic medications like morphine are frequently used.
Clonidine (Clon), which is another class of sedative-analgesic can be used for the similar
purpose but is more effective than morphine in decreasing shivering in adults and children.
Furthermore, in some preclinical studies, clonidine has been shown to be neuroprotective
(safe for the brain in models of brain injury). Clon (Duraclon┬«) has been approved by the
Food and Drug Administration (FDA)for the treatment of pain in certain cancer patients. It
is not approved for treating side effects of therapeutic hypothermia in infants and its use
in this study is considered investigational. FDA is allowing for us to use clonidine for
this Phase I-II study. In this kind of study clonidine will be started at low dose and
slowly increased do determine at what dose the shivering is controlled and the use of
clonidine is not associated with any side effects. This means that not all babies in the
study will get the same dose of Clon. Doses at the beginning of the study will be lower than
doses at the end of the study. Because of the design of the study, some babies may get
doses that are too low to have an effect, and other babies will probably might get a doses
that could cause side effects. In this Phase I-II study, the investigators will determine
the (i) the maximum tolerated dose of clonidine during cooling for HIE, (ii) the effects of
clonidine on heart rate, blood pressure, core body temperature and cerebral autoregulation
(ability to maintain constant blood flow in the face of blood pressure changes) and (iii)
association between blood levels and changes in the above parameters. In this study the
investigators hope to find ways to improve sedation, shivering and agitation in newborn
infants with HIE on the cooling protocol. Our ultimate goal is determine the potential
neuro-protective properties of clonidine in newborn babies with HIE.

Comparison of Epidural Fentanyl and Clonidine for Breakthrough Pain [Recruiting]
Epidural analgesia has proven to be an effective method for severe pain relief associated
with labor and delivery. During labor, a low dose continuous infusion of local anesthetic
and narcotic will be administered through an epidural catheter. As labor progresses and the
baby's head makes it way through the pelvis, breakthrough pain may emerge and often needs
further treatment. The investigators provide pain relief by administering analgesics through
the epidural catheter.
The patient will be randomly assigned to receive one of two medication mixtures believed to
be successful in treating this type of pain associated with advanced labor. After this
initial treatment, if pain relief is not attained, the patient may receive the other
medication as well. The medications used in this study have been used at this institution
for some time and have been found to be safe for mother and baby. The opioid (fentanyl) dose
is small and only a small fraction will be transmitted to the baby. The other medication
(clonidine) better known as a blood pressure medication has also been used for pain relief.
Studies and clinical experience have shown that clonidine when given epidurally in the doses
used in this study has minimal if any effect on the blood pressure of the mother or of the
baby. The investigators will record medical and obstetric history and labor progress
relevant to the patient. The patient will be asked questions regarding labor pain and side
effects before and after the analgesic is administered.
The primary objective is to determine which treatment regimen is more successful in
abolishing breakthrough pain in advanced labor.

Ropivacaine With Clonidine For Pediatric Rectus Sheath Blocks- The Magic Combination [Not yet recruiting]
Background: Millions of pediatric patients undergo laparoscopic surgeries every year and
many of them suffer significant pain and anxiety. Patient's anxiety correlates with the
severity of pain and effective postoperative analgesia is necessary for optimal recovery.
Single injections ultrasound guided rectus sheath blocks provide satisfactory postoperative
analgesia after pediatric laparoscopic appendectomy, however they are short lived. Searching
for a blocking agent that last long enough to outlast pain and has minimal side effects is a
difficult task. Using a combination of drugs yielded mixed results. Few pediatric studies
showed at best a weak trend in favor of clonidine prolonging analgesia after some blocks,
but anxiolytic properties of clonidine were not investigated. This study will compare rectus
sheath ropivacaine blocks with ropivacaine and clonidine blocks.
Methods: One hundred pediatric patients (10-17 years old) scheduled for laparoscopic
appendectomy will be double blinded and randomized to the two treatment groups: the
Ropivacaine Group will receive ropivacaine 0. 5% (10 ml) injected bilaterally in the
posterior rectus sheath, at the umbilicus location, and Ropivacaine Clonidine Group will
receive ropivacaine 0. 5% (10 ml) and clonidine (2mcg/kg). Post-operative analgesia will be
provided with ketorolac and acetaminophen around the clock, and morphine, or/and oxycodone
as needed. The primary aim is to determine if ropivacaine combined with clonidine prolongs
duration of paresthesia. The secondary aims are to determine if the use of clonidine
decreases anxiety level, prolongs duration of analgesia, and decreases pain severity at
umbilicus laparoscopic site, reduces the need for analgesics, improves satisfaction with
pain control, and is associated with complications such as oversedation, hypotension, and
Conclusions: Every hour of excellent analgesia count and a prolongation of block duration by
at least 50% is clinical relevant. The investigators hypothesize that rectus sheath
injections with ropivacaine and clonidine offer improved pain management compared to
