Clinical Pearls - Eye Signs
1. Bilateral Ptosis in a middle aged lady with a recent Right MCA infarct and old Left MCA infarct.
It occurs frequently in patients with hemispheric strokes, especially in association with right hemispheric lesions. Complete bilateral ptosis is usually caused by large infarctions and may be a premonitory sign of an impending herniation.Isolated b/l ptosis has been previously reported in association with midbrain lesions due to subacute encephalitis and midbrain hemorrhage.
Complete ophthalmoplegia, the combination of bilateral ptosis with loss of all extraocular movements, is rarely a consequence of ischemic stroke can be manifestation of bilateral paramedian midbrain-thalamic infarction.
2. Upward Gaze Deviation in a 26 year old man with hypoxic ischaemic brain damage secondary to cardiomyopathy and cardiac arrest.
This deviation is seen in hypoxic brain damage as their is loss of cerebellar Purkinje cells that normally balance vestibular and gaze - holding mechanisms.
In contrast tonic downward gaze deviation with small unreactive pupls is seen in camatose patients due to bilateral thalamic infarction or haemorrhage.

Intracerebral Haemorrhage
Both articles talk about medical management and emphasis on BP control as obvious to limit size of haematoma. Role of Factor VII is still controversial, associtaed with thromboembolic phenomenon with no survival benefit. Role and protocol of Prothrombinex is well given in both articles for warfarin induced ICH. Various antihypertensives and their doses are given in table form for ready reckoner in CCM article.

Simple way to reduce morbidity and mortality in surgical patients all over the world
www.nejm.org January 14, 2009 (10.1056/NEJMsa0810119)
A Surgical Safety Checklist to Reduce Morbidity and Mortality in a Global Population
Implementation of the checklist was associated with concomitant reductions in the rates of death and complications among patients at least 16 years of age who were undergoing noncardiac surgery in a diverse group of hospitals.
I suggest that this list should be posted in the surgeons clinic,pre-anaesthetic clinics and most importantly in pre-operative and operating theatres.
It is the simple things in life which when followed religiously lead to amazing results.

Keeping ourselves on track!!

Intensive care medicine recent articles, Dec'08
I have read these two articles and feel that they carry reasonable daily practice importance.
Review - a must read article: Renal replacement therapies: physiological review
Intensive Care Med (2008) 34:2139–2146
Maximizing rates of empiric appropriate
antibiotic therapy with minimized use
of broad-spectrum agents: are surveillance
cultures the key? Intensive Care Med (2008) 34:2130–2133
DOI 10.1007/s00134-008-1249-7
(This is just a summary of the article)E
EDITORIAL
Of the many therapeutic decisions, physicians have to face
in daily ICU practice choosing initial antibiotic therapy in
the patient with suspected severe nosocomial sepsis is one
of the more challenging.
In patients at risk for infection with multidrug
resistant (MDR) pathogens, the clinician has to resort to
broad-spectrum antimicrobials, which are themselves
linked with the emergence of multidrug resistance.
In this respect,appropriate empirical antibiotic therapy should
have a balanced antimicrobial spectrum that includes the
susceptibility of the infectious pathogen, but does not add
unnecessary selection pressure.
As an alternative to empirical combination antibiotic
therapy, a more focused initial antibiotic selection guided
by surveillance cultures (SC) has been reported.
As more reports solidify the clinical usefulness
of SC, cost remains probably the most important factor
prohibiting a general use of systematic SC.
ICUs with a high prevalence of MDR will
benefit the most, as will be patient populations with a high
risk for MDR infection, such as patients with a complex
history, a prolonged hospital stay and numerous previous
antibiotics. To reduce the cost one can consider restricting
surveillance to this ‘difficult’ patient category.
How to keep oneself updated in critcal care?
Beginning is Half done.
Lets congratulate Amit for his innovative idea of ongoing virtual meeting of like minded people.
It allows us to solve each other's clinical queries.
Let us set the ball rolling.
How one can keep oneself updated in the rapidly evolving field of critical care.
Yesterday's evidence is disproved today,for example hype of Glycemic control.
We have thought of following system.
I consider following journals have maximum impact on critical care practice all over the world.
1.NEJM
2.Intensive care medicine from ESICM
3.Critical care medicine from SCCM.
4.Critical care clinics.
5.Current opinion on critical care.
6.Critical care [Forum]
To some extant JAMA,LANCET,BMJ,CHEST,AJRCCM.
If we designate one journal each to one or two individual ,whose responsibility is to keep track of what is published in each issue and post summary of suggestions .
The suggestions include...worth reading article,breakthrough article,new idea but poor study etc etc.
This will enable all of us to keep updated but saves time of scanning each journal each month.
I will we very happy to know other ideas to get the same level of updates.

AMQ
Ok Harjit, we can start with you, put some question for which you are trying to get answer or some interesting experience in critical care.
Congratulations!
It is said that necessity is the mother of all inventions and innovations, and at present the most important need of the hour is to help others with what we have learnt over the years.And what better medium than the Internet to help us achieve this.
Let us spare some time for this ongoing process and hope that we are able to do some service to the mankind and those who need it most.
The simplest way to start any forum is to start asking questions.So, it would be a good idea to start a section on-- ANSWER MY QUERY (AMQ in short).In which we/anybody puts a question/s on the blog and the answer will be provided by some one who either knows the answer or has the time to answer that/those question/s.The questions will come from our everyday practice as we come across the patients/situations/equipment.If we are not able to provide the answer we should at least provide a reference or an authentic link.
To be continued.
